Synopsis

Remote host is affected by a xss vulnerability.

Description

The version of FortiWeb installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-20-122 advisory.

 - An improper neutralization of input during web page generation in FortiWeb GUI interface 6.3.0 through 6.3.7 and version before 6.2.4 may allow an unauthenticated, remote attacker to perform a reflected cross site scripting attack (XSS) by injecting malicious payload in different vulnerable API end-points.
 (CVE-2021-22122)

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

Solution

Please upgrade to FortiWeb version 6.2.4/6.3.8 or later.
