River Past CamDo 3.7.6 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code 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 to trigger code execution and establish a bind shell on port 3110.
AnalysisAI
River Past CamDo 3.7.6 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious string in the. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. River Past CamDo 3.7.6 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code 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 to trigger code execution and establish a bind shell on port 3110. Affected products include: Riverpast River Past Camdo.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
