CVE-2024-57542Public exploit

Unauthenticated command execution via unchecked JSON field

Published Jan 21, 2025 · Updated Jan 22, 2025

Command injection in Linksys E8450 firmware 1.2.00.360516 allows remote attackers on an adjacent network to execute OS commands. The portal.cgi handler's sub_422eb8 JSON parser passes the untrusted id_email_check_btn field directly as an argument to system(). Unauthenticated adjacent-network access is sufficient, enabling command execution with the router service's privileges.
