A flaw was found in FFmpeg's DASH playlist support. This vulnerability allows arbitrary HTTP GET requests to be made on behalf of the machine running FFmpeg via a crafted DASH playlist containing malicious URLs. The severity level is classified as high with a CVSS score of 7.2, indicating significant risk to affected systems. Organizations using FFmpeg should take this vulnerability seriously, as it could lead to unauthorized actions being performed on their behalf.
Risk to organizations includes potential data exposure and unauthorized access to resources. The exploitation status of this vulnerability shows that no public exploit has been confirmed, but the nature of the vulnerability means that it could be exploited if left unaddressed. Organizations should prioritize patching immediately.
The urgency for defenders is high. With the potential for network exploitation at a low complexity and no privileges required, this vulnerability poses a significant threat to environments using affected versions of FFmpeg.
Therefore, it is critical that organizations running FFmpeg review their systems and apply necessary updates to mitigate this vulnerability.
Vulnerability Details
This vulnerability allows arbitrary HTTP GET requests to be made on behalf of the machine running FFmpeg via a crafted DASH playlist containing malicious URLs. The vulnerability is categorized under CWE-99, which pertains to improper control of a resource through its lifetime. The CVSS score of 7.2 indicates a high severity, with an attack vector classified as NETWORK, low attack complexity, and no privileges or user interaction required.
FFmpeg versions from 2.0 to 6.0 are affected by this vulnerability. The flaw was published on January 6, 2025, and has been modified since its initial discovery.
Technical Analysis
The root cause of this vulnerability lies in FFmpeg's handling of DASH playlists. By crafting a malicious DASH playlist, attackers can send arbitrary HTTP GET requests. The attack vector is network-based, requiring no privileges or user interaction, allowing for easy exploitation. The impact on confidentiality and integrity is low, while availability is unaffected.
Risk & Impact Analysis
Organizations using FFmpeg may face significant risks due to this vulnerability. The blast radius could be extensive, as it allows for arbitrary requests to be executed on behalf of the user running FFmpeg. Although the EPS score is low, organizations should not underestimate the potential for misuse. The urgency for organizations to address this vulnerability is high, given the nature of the exploitation capability.
