Vulnerability details
The vulnerability allows a remote privileged user to execute arbitrary OS commands on an in-group managed server using stored SSH credentials, potentially gaining root privileges.
The vulnerability exists due to OS command injection in the Roxy-WI WAF rule-save endpoint when interpolating the unvalidated save parameter into systemctl or Docker shell commands before enforcing an action allowlist. A remote privileged user can submit a save value containing a newline as a role 2 group administrator, even without the corresponding service entitlement, to execute additional commands with the stored SSH account's authority.
