Vulnerability Data

Parseable is a log analytics platform built for high-volume data ingestion and analysis. Prior to 3.0.0, src/handlers/http/middleware.rs uses unwrap() while parsing the x-amz-firehose-common-attributes header before authentication. A remote unauthenticated attacker can supply non-UTF-8 header data, malformed JSON, or invalid derived…

header values that trigger a Rust panic and interrupt request handling, allowing repeated requests to deny service or cause container restart loops. This issue is fixed in version 3.0.0.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-24 Fail in Known State
addresses: CWE-703 CWE-248

Mandates explicit, predictable handling of exceptional conditions rather than undefined continuation.

SI-17 Fail-safe Procedures
addresses: CWE-703 CWE-248

Requires explicit, safe handling actions for specified exceptional conditions rather than allowing unchecked propagation or default unsafe behavior.

AU-5 Response to Audit Logging Process Failures
addresses: CWE-703

Implements explicit check and handling for the exceptional condition of audit logging process failure.

CA-7 Continuous Monitoring
addresses: CWE-703

Establishing and monitoring system metrics with correlation and response actions helps identify and address improper handling of exceptional conditions.

CP-12 Safe Mode
addresses: CWE-703

Provides a defined response to detected conditions by restricting operation, ensuring exceptional conditions are handled rather than ignored or mishandled.

CP-3 Contingency Training
addresses: CWE-703

Contingency training equips users with defined procedures to check and respond to exceptional conditions during disruptions, reducing exploitation of mishandled errors.

CP-4 Contingency Plan Testing
addresses: CWE-703

Testing verifies the system's ability to detect, handle, and recover from exceptional conditions as part of the plan, reducing exploitability of improper exception handling.

CP-5 Contingency Plan Update
addresses: CWE-703

Regular updates keep contingency procedures aligned with system changes, providing structured handling for exceptional conditions that would otherwise allow unmitigated exploitation.

prevents

Secure coding standards directly require catching and handling exceptions to prevent crashes or leaks.

A.8.29 Security testing in development and acceptance partial match
finds

Security testing can detect uncaught exceptions before production deployment.
