CVE-2025-5444Public exploitNetwork attack vector

Authenticated command execution via unsanitized form parameters

Published Jun 2, 2025 · Updated Jun 2, 2025

OS command injection in Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 allows authenticated command execution. The RP_UpgradeFWByBBS handler in mod_form.so passes the type, ch, ssidhex, security, extch, pwd, mode, ip, nm, and gw form values into an operating-system command without neutralizing shell metacharacters. A valid web session is required by the demonstrated request, and successful injection provides a shell with the extender's command-execution privileges.
