Summary

In VIVOTEK FD8136 firmware version FD8136-VVTK-0300a, a stack-based buffer overflow exists in motion_privacy.cgi. An authenticated attacker can remotely execute arbitrary code as root by sending an oversized n1 parameter in a POST request to the relevant CGI endpoints.

Risk Assessment

An attacker can fully compromise the camera, leading to espionage, surveillance disruption, or use of the device as an entry point into the network.

Recommendation

Immediately update the camera firmware to a patched version or restrict administrative access to trusted networks.

Original NVD description (English source)

A stack-based buffer overflow in the motion_privacy.cgi binary in VIVOTEK FD8136 firmware FD8136-VVTK-0300a allows authenticated remote attackers to execute arbitrary code as root via an oversized n1 parameter in a POST request to the /cgi-bin/admin/setpm.cgi, /cgi-bin/admin/setmd.cgi, or /cgi-bin/admin/setmd_profile.cgi endpoint (all symlinks to the same binary). The parameter value is copied into a fixed-size 0xa4-byte stack buffer without bounds checking, overwriting the saved link register. The binary is compiled without stack canaries.
