They should also review configurations, monitor for suspicious activity, and implement compensating controls where necessary. Vulnerability management and security teams should prioritize verifying FFmpeg versions and applying patches to prevent potential SSRF attacks.

Why it matters

Defenders should care about this vulnerability as it allows malicious RTSP servers to probe internal network services, potentially leading to SSRF attacks.

• Potential SSRF attacks on internal network services
• Bypassing of -protocol_whitelist configurations
• Probing of internal hosts and ports

Technical summary

FFmpeg before 7.1.4 and 8.0.2 contains a server-side request forgery vulnerability in ff_rtsp_connect() in libavformat/rtsp.c, allowing malicious RTSP servers to redirect FFmpeg to internal hosts and ports under other schemes, bypassing -protocol_whitelist, to probe internal network services. This vulnerability affects FFmpeg installations and defenders should assess exposure and apply patches accordingly. The vulnerability is triggered by RTSP 3xx redirects without validating the Location URL, which can lead to SSRF attacks.

Defenders should prioritize verifying FFmpeg versions and applying patches to prevent potential SSRF attacks.

Recommended defensive actions

• Verify FFmpeg versions and apply patches
• Review and update -protocol_whitelist configurations
• Monitor for suspicious RTSP activity
• Perform vulnerability scanning
