TITLE

VIVOTEK Inc. of Network Camera FD8136 Stack-based buffer overflow vulnerability in firmware

Trust: 0.8

sources: JVNDB: JVNDB-2026-018164

DESCRIPTION

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. The value of this parameter is fixed in size. - Some of the information handled by the software may be overwritten. - Some parts of the software may stop working
