"A declared config flag disables a required +approval gate for high-risk actions, independent of any instruction +text" is a mechanism.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ] + }, { "ave_id": "AVE-2026-00014", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index afadb54..8a0c1a9 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 77, - "generated_at": "2026-08-13T15:39:05.714Z", + "record_count": 80, + "generated_at": "2026-08-14T15:35:31.620Z", "source": "https://github.com/aveproject/ave" } diff --git a/docs/specs/researcher-process.md b/docs/specs/researcher-process.md index 3c9290b..94a3783 100644 --- a/docs/specs/researcher-process.md +++ b/docs/specs/researcher-process.md @@ -131,10 +131,60 @@ actually checks for, not a padded ideal: `aivss.thm`, `aivss.mitigation_factor`, `aivss.aivss_score`, `aivss.aivss_severity`, `aivss.spec_version` -**Optional, omit rather than force a fit** -- `owasp_asi`, `owasp_mcp`, `mitre_atlas`, `nist_ai_rmf`: only include a - mapping you can actually defend field by field, not because a record - feels like it should have one +**Governance and framework mappings — the fields a CISO reads first** +These four crosswalk fields are what lets a security team map an AVE +record onto the frameworks they already report against.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": ["llm", "sandbox"], + "derivable_into": ["privilege-escalation-chain"] +} diff --git a/tests/fixtures/AVE-2026-00078_negative.md b/tests/fixtures/AVE-2026-00078_negative.md new file mode 100644 index 0000000..50548eb --- /dev/null +++ b/tests/fixtures/AVE-2026-00078_negative.md @@ -0,0 +1,29 @@ +# Multi-agent trace: "what is the compound's melting point" research task (reviewed) + +Orchestrator dispatches the same sub-task to two parallel researcher +agents, `researcher-a` and `researcher-b`, then to an `analyst` agent +that synthesizes their findings into the final answer. + +``` +researcher-a calls chemical-database-lookup("compound: X-47") + tool returns: { "melting_point_c": 812, "source": "NIST WebBook" } +researcher-a reports: "Melting point confirmed at 812°C via NIST WebBook." + +researcher-b calls chemical-database-lookup("compound: X-47", mirror: "cas") + tool returns: { "melting_point_c": 812, "source": "CAS Registry" } +researcher-b reports: "Melting point confirmed at 812°C via CAS Registry." + +analyst receives both reports, confirms both cite an actual tool-call +span in the trace, confirms both independently-sourced figures agree +(812°C from NIST WebBook and CAS Registry respectively), and only then +accepts 812°C as the final answer, noting the cross-source agreement +in its own output. +``` + +Both parallel researchers' claims are backed by real, distinct tool-call +spans in the trace, and the analyst's acceptance step explicitly compares +the two independent results before committing to an answer -- a quorum +of two independently-sourced, tool-verified figures that agree, not a +single unverified claim accepted on its own.

Typically, details get +lost that way."* Went back and independently re-derived each candidate +using OpenCRE's own `/rest/v1/text_search` against AVE's own mechanism +language directly (single-word queries — the live search endpoint +404s on multi-word phrases regardless of encoding, an API quirk, not a +content finding), *before* looking at what the CWE-routed answer had +been, then compared. + +**Result: four of five held up unchanged under independent search. One +did not, and the independent method found something CWE-routing +structurally could not have** — documented as candidate 4 below, kept +as the clearest demonstration of exactly the risk CONTRIBUTING.md +names, not smoothed over. + +### 1. AVE-2026-00047 (Hardcoded Credentials in Agent Component) → CWE-798 → CRE `774-888` + +- **AVE mechanism** (from the record's own `behavioral_fingerprint`): + "Skill file contains a high-entropy string adjacent to a credential + keyword such as api_key, secret, token, password... a literal value, + not an environment variable reference or secrets manager path." +- **CRE 774-888's own name**: "Do not store secrets in the code." +- **Correspondence**: direct, one-sentence match. AVE's behavioral + fingerprint is a detection-shaped restatement of exactly what this CRE + prohibits. No forcing needed. +- **Independent re-check**: `text_search?text=secret` surfaces `774-888` + directly (alongside `223-780` "Secret storage," a DSOMM-sourced parent + concept, not a competing leaf). Holds up. +- **Confidence: high.** + +### 2. AVE-2026-00061 (TLS Certificate Verification Disabled) → CWE-295 → CRE `430-636` + +- **AVE mechanism**: "sets a flag that disables TLS certificate + verification for its own outbound connections... any network position + capable of intercepting the connection can perform a + machine-in-the-middle attack." +- **CWE-295 links to 8 CREs on OpenCRE**, most of them about OTP/MFA + weaknesses (`354-753`, `816-631`, `646-227`, `168-186`, `404-126`) — + a different failure mode sharing the same broad CWE. The one that + actually matches is `430-636`, whose own name is: **"Verify TLS + certificates and trust chain."** +- **Correspondence**: direct. This is the clearest illustration in this + pilot of why "topic feels adjacent" isn't the bar — 7 of the 8 CREs + linked under CWE-295 would have been a wrong mapping despite sharing + the identical CWE citation. +- **Independent re-check**: `text_search?text=certificate` alone does + *not* surface `430-636` in its top results (returns encryption-at-rest + and session-token CREs instead — a noisy single-word query). Retried + with `text_search?text=TLS`, which does surface `430-636` directly, + alongside a cluster of other real TLS-related CREs (disabling + insecure SSL/TLS versions, protocol fallback, algorithm strength, + mutual auth). `430-636` remains the most precise of that cluster for + AVE-2026-00061's specific mechanism (certificate/trust-chain + verification being disabled, not cipher strength or protocol version). + Holds up, with the caveat that the right search term mattered more + than expected. +- **Confidence: high.** + +### 3. AVE-2026-00053 (MCP Resource Path Traversal) → CWE-22 → CRE `675-168` + +- **AVE mechanism**: "An MCP resource or file-handler tool's own + path-validation logic fails to canonicalize a caller-supplied path... + allowing directory-traversal sequences... to escape the tool's + declared scope." +- **CRE `675-168`'s own name**, first glance, reads narrower than + expected: "Sanitize filename metadata from untrusted origin if + processing is required" — worth checking whether "filename metadata" + means something narrower than path/URL traversal generally (e.g. file + upload metadata specifically) before trusting it. +- **Checked its full link list directly**: linked to CWE-22 through + CWE-40 (the entire MITRE path-traversal CWE family), CAPEC-126 "Path + Traversal" plus four related CAPEC entries, five ZAP path-traversal + scan rules, and its own ASVS anchor text spells out the real scope: + *"Verify that user-submitted filename metadata is not used directly by + system or framework filesystems and that a URL API is used to protect + against path traversal."* "Filename metadata" is OpenCRE/ASVS's own + phrase for "a user-controlled filename/path value" generally, not a + narrower upload-specific concept. Confirmed correct scope. +- **Independent re-check**: `text_search?text=traversal` surfaces + `675-168` as the top result, repeated across CWE-22/24/27/28 entries + all pointing at the same CRE — the strongest, cleanest corroboration + of any candidate in this pilot. Holds up. +- **Confidence: high, after the deeper check** (would have been + "plausible but unverified" without it). + +### 4. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00034 (Dynamic Third-Party Skill Import) → CRE `307-507` (primary), CRE `777-470` and CRE `577-260` (secondary) + +**This is the candidate the independent-search pass actually changed — +kept as the pilot's central finding, not edited away.** + +- **AVE mechanism**: "Loading code from an external URL at runtime + without verification... effectively delegates code execution to an + attacker-controlled source." The record itself cites both CWE-829 + (Inclusion of Functionality from Untrusted Control Sphere) and CWE-494 + (Download of Code Without Integrity Check). +- **First pass (CWE-routed)** found `777-470` "Ignore/block execution + logic from untrusted sources" and `577-260` "Enforce integrity check + for externally hosted assets (eg SRI)," both via CWE-829's own linked + CREs. Both are real, defensible matches — documented below as + secondary. +- **Independent re-check**, run *without* looking at the CWE-829 answer + first: `text_search?text=plugin` and `text_search?text=third-party` + (drawn from AVE-2026-00034's own title, not its CWE citation) both + surface **CRE `307-507`**, whose full name is *"Allow only trusted + sources both build time and runtime; therefore perform integrity + checks on all resources and code"* — and whose own ASVS anchor text is: + *"The application must not load or execute code from untrusted + sources, such as loading includes, modules, **plugins**, code, or + libraries from untrusted sources or **the Internet**."* That is close + to a verbatim restatement of AVE-2026-00034's own mechanism + ("load the plugin from https://external.site/plugin.py"). +- **`307-507` links to CWE-353** ("Missing Support for Integrity Check") + — a *different* CWE than CWE-829/494, the ones AVE-2026-00034 itself + currently cites. The CWE-routed first pass could not have found this + CRE by construction: it only ever looks at CREs already reachable from + a CWE the AVE record happens to name. This is the concrete instance of + the exact risk `CONTRIBUTING.md` names — not a hypothetical, one that + happened during this pilot's own first draft. +- **Resolution**: propose `307-507` as the primary link (single closest + mechanism match, found independently of the record's own citations), + and keep `777-470`/`577-260` as secondary/companion links — both are + still real, defensible, and OpenCRE's own data model routinely + supports one Standard linking to several CREs (`CWE:16` alone links to + 5). Also worth carrying back into AVE's own corpus separately from + this pilot: AVE-2026-00034's own `references` could reasonably add + CWE-353 alongside its existing CWE-829/494 citations, since this + search surfaced a real angle on the mechanism AVE's own record + doesn't currently name. Not done in this draft — flagged for a + follow-up, kept out of scope here to avoid conflating the OpenCRE pilot + with an unrelated AVE record edit. +- **Confidence: high on `307-507` specifically because it was found + independently; still high but secondary on the other two.** +- **Second-pass review note**: `307-507`'s own full link list (13 links; + the earlier fetch during drafting only printed the first 8) confirms + CWE-353 is its *only* linked CWE — no CWE-829/494 present anywhere on + it, so the "CWE-routing structurally could not have found this" claim + above holds on the complete data, not a truncated sample. It also + carries a `Related` (not `PartOf`) link to `613-285 Supply chain + management` — the same node that sits in `577-260`'s own parent chain. + OpenCRE's own graph already treats these two CREs as connected to each + other, independent confirmation that proposing both together for one + AVE record is coherent with the existing graph, not an arbitrary + combination assembled for this pilot. + +### 5. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00033 (Unsafe Deserialization or Eval Instruction) → CWE-502 → CRE `736-554` + +- **AVE mechanism**: "Deserializing untrusted data using unsafe methods + like Python's `pickle.loads`, unguarded `yaml.load`, **or `eval`/`exec` + on arbitrary strings**...

This crosswalk matches against those 11 rules' real logic, not their names alone, since the two do not always agree (see the hardcoded_c2 gap below).\n\nThe open question from the outreach, whether constraint-guided representation synthesis generalizes onto AVE's behavioral classes or stays genuinely distinct from pattern-based classification, has a real, mixed answer: partial generalization, clean where a Semia rule terminates in a specific effect AVE also names explicitly, genuinely distinct where AVE's granularity is organized by attack narrative and Semia's is organized by dataflow destination. 16 mappings verified across 9 of Semia's 11 rules, field-checked against provenance_vector and behavioral_fingerprint, not category labels.\n\nThree concrete, citable examples of the real daylight: (1) label_unsanitized_context_ingestion (any untrusted value reaching one of five high-priv effects, ungated) keyword-sweeps against roughly two dozen of AVE's prompt-injection-flavored records, but only genuinely verifies against ones that name a specific privileged sink (AVE-2026-00006's crypto_sign, AVE-2026-00042's code_eval); most of AVE's prompt-injection catalog describes the injection vector itself (jailbreak, hidden instruction, context window manipulation, multi-turn persistence) without asserting a terminating privileged effect, so a keyword match is not a structural one. AVE splits by injection surface; Semia collapses by dataflow destination. (2) A rule's own name can promise a match its logic does not deliver: label_hardcoded_c2_communication reads like an obvious fit for AVE-2026-00073 (Static Endpoint Redirect), but the actual Datalog condition requires call_code=\"unresolved_target\", a destination static analysis cannot resolve at all, while AVE-2026-00073's mechanism is the opposite: a fully resolved, literal, committed bad destination. No AVE record currently satisfies this rule's real condition; left unmapped rather than forced. (3) A shape can sit a full abstraction level above what Semia's fact model can represent: AVE-2026-00070 (Distributed Cross-Agent Backdoor Fragments) shares label_dormant_malicious_payload's dormant-until-reassembled narrative, but the mechanism spans multiple agents' memories with an offline, external reassembly step, and Semia's CORE_SCHEMA models exactly one skill() per analysis pass with no multi-agent or cross-session concept in the schema at all. Not a missing rule, a missing dimension; left unmapped.\n\nTwo more things worth surfacing. First, AVE-2026-00003 (Credential exfiltration via agent instruction) is matched by two of Semia's own rules independently, label_implicit_egress_channels (an explicit dataflow edge from a secret value to an untrusted egress call) and label_shadow_credentials (co-presence of a secret-region read and an untrusted-egress-capable skill, checked without requiring an explicit edge), two differently-reasoned Datalog conditions inside one tool converging on the same AVE id. Combined with this record's existing cfgaudit, nova-proximity, and Ramparts matches (see those crosswalks), it is now the record with the broadest independent confirmation across AVE's whole crosswalk set, four separate tools, none sharing code, plus one tool's own two internal rules.

Substantially larger surface than skillsentry, closer in caliber to Ramparts/nova-proximity/Semia.\n\nThree findings worth stating directly rather than leaving implicit. First, the injection category (INJ001-006: eval()/exec() with a non-literal argument, os.system, subprocess shell=True) reads like an obvious match for AVE-2026-00052, but these are pure regex signature matches over dangerous syntax, not a traced dataflow from a caller-supplied parameter to the sink; AVE-2026-00052's own fingerprint specifically requires that taint path. This is the exact same signature-vs-reachability distinction the Ramparts crosswalk already documented for its own CommandInjection rule against this same AVE record, so it is treated the same way here: left as a gap, not forced. Second, IOCDetector matches against a curated malicious IP/domain/URL database, a reputation-list lookup, which is a structurally different approach from AVE's own stated design principle (behavioral fingerprints over signatures, CLAUDE.md hard rule 3); it has no AVE counterpart by design, not by gap. Third, LLMAnalyzer produces free-form findings from an LLM's own judgment with no fixed taxonomy of its own, so there is nothing stable to crosswalk against; left out entirely rather than mapped to a placeholder.\n\nThe persistence category (PER001-007) is close to exhaustive against AVE-2026-00008, which is itself the strongest single match found across either tool in this pass: six of seven rules verify directly against the record's own named examples (cron, systemd, shell-profile modification), and the seventh (a Windows registry Run key) verifies against the fingerprint's general 'executes on login or reboot' language even though the record's own examples are Unix-flavored. The privilege_escalation category (PRI001-005: sudo, chmod 777/+s, setuid/setgid) is a clean, complete miss: AVE's whole Privilege Escalation attack_class operates at the agent/permission-model level (scope creep, delegation, trust transfer), one abstraction level above OS-level Unix privilege primitives, which have no AVE analog at all today.
