Unauthenticated command execution via changePerm mode injection

Published Sep 19, 2025 · Updated Sep 19, 2025

OS command injection in Control Web Panel before 0.9.8.1205 allows remote attackers to execute commands without authentication. The filemanager changePerm handler inserts the unvalidated t_total permission value into a shell-executed chmod command, so metacharacters invoke additional commands. Exploitation requires knowledge of a valid non-root username and runs injected commands with that user's Linux account privileges.
