Technical details
The XML-RPC servlet is configured to accept non-standard vendor extension types that are deserialized during request parsing before any authentication checks occur. The servlet endpoint remains accessible regardless of whether the global XML-RPC feature is enabled or disabled, allowing attackers to trigger deserialization of untrusted bytes. This can lead to arbitrary code execution with the privileges of the application.
