Medium Nessus Plugin ID 104886


The remote host is affected by a cross-site scripting vulnerability.


The version of Fortinet FortiOS running on the remote device is 5.0.x prior to 5.2.13, 5.4.x prior to 5.4.7, or 5.6.x prior to 5.6.3. It is, therefore, affected by Cross-site Scripting (XSS) vulnerability that may allow an authenticated user to inject arbitrary web code or HTML in the context of the victim's browser via the login redir parameter.

Note that Nessus has not checked for special builds.
