CVE-2025-29064Network attack vector

Unauthenticated code execution via CGI code injection

Published Apr 3, 2025 · Updated Apr 7, 2025

Code injection in TOTOLINK X18 9.1.0cu.2024_B20220329 allows remote attackers to execute arbitrary code through cstecgi.cgi. The public record identifies sub_410E54 as the affected function, but the sole linked technical report is unavailable and the unsafe operation on request data is not publicly disclosed. No authentication or user interaction is required, and successful exploitation grants arbitrary code execution on the router.
