Description
OpenAM before 16.1.3 contains an unauthenticated arbitrary class instantiation vulnerability in the legacy JAX-RPC SOAP interface that allows remote attackers to load classes without authentication. Attackers can send SOAP requests to /jaxrpc/* with an unverified session identifier and a chosen class name, crashing the server, probing the classpath, or potentially reaching code execution via gadget chains.
