CVE-2026-11450Public exploitNetwork attack vector

Unauthenticated command execution via truncated device validation

Published Jun 7, 2026 · Updated Jun 7, 2026

Command injection in GL.iNet Beryl AX firmware 4.4.5 allows remote attackers to execute commands through the unauthenticated CGI endpoint. The glc dispatcher loads nas-web.so and resolves eject_disk_do1 without authentication; disk_remove_do validates a 64-byte-truncated dev_name but inserts the longer value into a shell command. Consecutive slashes reduce the checked prefix to /dev/null while trailing command substitution reaches system(), yielding root command execution without credentials.
