The IBM WebSphere Application Server running on the remote host is version 9.0.x prior to 9.0.5.3. It is, therefore, affected by a denial of service (DoS) vulnerability in the Apache CXF library used by the WebSphere Application Server, which does not restrict the number of message attachments present in a given message. An unauthenticated, remote attacker can exploit this, by crafting a message containing a very large number of message attachments, in order to cause a denial of service condition.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
