CVE-2024-0943Public exploitNetwork attack vector

Protected-information disclosure via unexpired sessions

Published Jan 26, 2024 · Updated Oct 18, 2024

Insufficient session expiration in TOTOLINK N350RT 9.3.5u.6255 allows remote attackers to retain access through cstecgi.cgi. The public record identifies an unspecified function in /cgi-bin/cstecgi.cgi but does not disclose which session token remains valid or how expiration fails. Network reachability and a difficult request sequence are required, and the documented consequence is limited to protected-information disclosure.
