The IBM WebSphere Application Server running on the remote host is version 7.0.0.0 through 7.0.0.45, 8.0.0.0 through 8.0.0.15, 8.5.0.x prior to 8.5.5.18, or 9.0.x prior to 9.0.5.4. It is, therefore, affected by a remote code execution vulnerability. An authenticated, remote attacker can exploit this by sending a specially crafted sequence of serialized objects to cause remote code execution on the system.
