Deeper analysisAI

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.
