"The remote SAP NetWeaver ABAP server may be affected by a cross-site scripting (XSS) vulnerability. A cross-site
scripting (XSS) vulnerability exists 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.");
