CVE-2024-57539Public exploitNetwork attack vector

Unauthenticated command execution via userEmail shell injection

Published Jan 21, 2025 · Updated Feb 4, 2025

Command injection in Linksys E8450 firmware 1.2.00.360516 allows remote attackers to execute operating-system commands via userEmail. The portal.cgi register_email path passes the parsed userEmail JSON field directly to system without neutralizing shell metacharacters. No authentication or user interaction is required, and injected commands run with the privileges of the router's web-management process.
