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 8.5.5.19, or 9.0.x prior to 9.0.5.6. It is, therefore, affected by an information disclosure vulnerability. An unauthenticated, remote attacker can exploit this by sending a specially crafted sequence of serialized objects.
Note that Nessus has not tested for this issue but has instead relied only on the applicationโs self-reported version number.
