CVE-2025-50612Public exploitNetwork attack vector

Unauthenticated service crash via oversized wl_sec_set

Published Aug 13, 2025 · Updated Aug 14, 2025

Buffer overflow in cgitest.cgi in Netis WF2880 2.1.40207 allows remote attackers to crash the CGI process via a crafted request. FUN_004743f8 retrieves the attacker-controlled wl_sec_set value from a table built from CGI input and copies the oversized value without checking the destination buffer size. No authentication or user interaction is required, and the demonstrated consequence is a process crash that interrupts service rather than code execution.
