CVE-2024-42633Public exploitNetwork attack vector

Root command execution via unvalidated language parameter

Published Aug 19, 2024 · Updated Aug 20, 2024

OS command injection in Linksys E1500 Firmware 1.0.06.001 allows remote authenticated users to execute commands with root privileges. The do_upgrade_post function reads detect_lang from NVRAM, formats it with snprintf, and passes the result to system without validation. Access to the authenticated apply.cgi language-change request is required, and injected commands run with root privileges.
