TITLE

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

Trust: 0.8

sources: JVNDB: JVNDB-2026-018163

DESCRIPTION

A stack-based buffer overflow in the export_language.cgi binary in VIVOTEK FD8136 firmware FD8136-VVTK-0300a allows authenticated remote attackers to execute arbitrary code as root via a crafted POST request to the /cgi-bin/admin/export_language.cgi endpoint. The handler passes the attacker-controlled Content-Length value directly to fread() as the read size into a fixed-size 0x60-byte stack buffer, overwriting the saved link register. The binary is compiled without stack canaries. The handler is controlled by the attacker. - Some of the information handled by the software may be overwritten. - Some parts of the software may stop working
