CVE-2026-35717 (GCVE-0-2026-35717)

Vulnerability from cvelistv5 – Published: 2026-06-02 00:00 – Updated: 2026-07-05 01:36
VLAI
Summary
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.
