A flaw exists in the Opto22 Groov Manage REST API that could allow for remote code execution with root privileges. The issue arises when a POST request is sent to a vulnerable endpoint. The application improperly handles header details from the request, using them to construct commands without sufficient safeguards. This allows an attacker with administrative access to inject and execute arbitrary commands as root. The vulnerable endpoint processes POST requests and utilizes header information to build commands. The vulnerable parameters are within the request headers.

The issue allows attackers with permission to create or configure various objects to inject crafted content into Old Data Monitor, resulting in the instantiation of potentially unsafe objects once discarded by an administrator. This is possible because when deserialization fails due to invalid data, Jenkins stores invalid object references created through XML REST APIs in the Old Data Monitor. If an administrator discards the old data, some erroneous data submitted to these endpoints may be persisted. Attackers with View/Create, Job/Create, Agent/Create, or their respective */Configure permissions can exploit this.
