"A cross-site scripting (XSS) vulnerability exists in SAP NetWeaver AS ABAP 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.");
