The IBM WebSphere Application Server running on the remote host is version 7.0.0.x through 7.0.0.45, 8.0.0.x through 8.0.0.15, 8.5.0.x prior to 8.5.5.14, or 9.x prior to 9.0.0.8. It is, therefore, affected by a vulnerability in the Apache Struts subcomponent deu to an error in the MultiPageValidator implementation. An unauthenticated, remote attacker can exploit this, using a modified page parameter, to bypass restrictions and launch further attacks on the system.

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
