Summary

CVE-2023-6601 is a medium-severity Resource Injection (CWE-99) vulnerability in Ffmpeg Ffmpeg. Its CVSS base score is 4.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 34th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

SI-10 Information Input Validation good match

Directly requires validation of inputs before they are accepted as resource identifiers.

AC-3 Access Enforcement partial match

Enforces authorizations on resource access so an injected identifier cannot reach outside the intended sphere.

AC-4 Information Flow Enforcement partial match

Enforces information flow rules that block use of untrusted identifiers to reach unauthorized resources.

AC-6 Least Privilege partial match

Least privilege limits the damage an injected code fragment can perform once executed.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
blocks

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-99, a class-level weakness, and none of its children carries one either.
