Remote command execution via attacker-supplied Invoke scripts
Published Feb 17, 2022 · Updated Jul 9, 2026
Remote code execution in O2OA 6.4.7 allows remote attackers to execute operating-system commands through the Invoke API. The /x_program_center/jaxrs/invoke handler accepts attacker-supplied JavaScript, stores it as an enabled Invoke, and later evaluates it with access to java.lang.Runtime.exec. The published proof of concept obtains authorization with the documented default xadmin credentials before creating the Invoke, then launches /bin/bash and returns command output.
