The IBM WebSphere Application Server running on the remote host is version 8.5.0.x prior to 8.5.5.16 or 9.0.x prior to 9.0.5.0. It is, therefore, affected by a cross-site scripting vulnerability in the WebSphere Application Server Admin Console due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user’s browser session.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
