Summary

CVE-2023-6605 is a high-severity Resource Injection (CWE-99) vulnerability in Ffmpeg Ffmpeg. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-6605 is a vulnerability in FFmpeg's DASH playlist support that enables arbitrary HTTP GET requests to be issued on behalf of the machine running FFmpeg. This flaw is triggered by processing a crafted DASH playlist containing malicious URLs. The affected software is FFmpeg, with a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N) and is associated with CWE-99.

Remote unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. By supplying a malicious DASH playlist to an FFmpeg instance, attackers cause it to perform HTTP GET requests to attacker-specified URLs, potentially enabling server-side request forgery scenarios that impact confidentiality and integrity with a changed scope.

Advisories detailing patches and mitigations are available from Red Hat Bugzilla at https://bugzilla.redhat.com/show_bug.cgi?id=2334336 and the Debian LTS announcement at https://lists.debian.org/debian-lts-announce/2025/07/msg00004.html.

Mitigating Controls (NIST 800-53 r5) AI

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and sanitization that prevent resource-identifier injection flaws.

PR.AA-05 partial match
prevents

Least-privilege access policy and enforcement limits damage from injected resource identifiers even when input validation is absent.

PR.IR-01 partial match
prevents

Network segmentation and unauthorized-access controls reduce the blast radius of successful resource injection.

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

Security testing can detect resource-injection flaws but does not itself implement preventive controls.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and resource-identifier sanitization that directly prevents resource injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls on external identifiers used to access resources.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce attack surface for resource injection but do not prescribe identifier validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards require strict validation and whitelisting of all resource identifiers before use.

A.8.3 Information access restriction partial match
mitigates

Information-access-restriction policies limit which resources can be referenced, indirectly reducing injection impact.
