River Past CamDo 3.7.6 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code. The vulnerability is triggered by supplying a malicious string in the Lame_enc.dll name field. Attackers can craft a payload with a 280-byte buffer, NSEH jump instruction, and SEH handler address pointing to a pop-pop-ret gadget. Successful exploitation leads to code execution and establishment of a bind shell on port 3110. This is a local privilege escalation vulnerability affecting the multimedia software application.
