Technical details

The phpini_editor module in CWP before version 1.16 suffers from two vulnerabilities: (1) the acc=update action uses file_put_contents without path confinement, allowing arbitrary file writes to attacker-specified paths, and (2) the acc=addlabelphpiniadv action passes unsanitized user input directly to shell_exec without escaping, enabling OS command injection. Both vulnerabilities require authentication and module access, but together enable remote code execution.
