Juniper ScreenOS 6.3.x < 6.3.0r24 Multiple XSS (JSA10782)

Low Nessus Plugin ID 101840

Synopsis

The remote host is affected by multiple cross-site scripting vulnerabilities.

Description

The version of Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r24. It is, therefore, affected by multiple cross-site scripting (XSS) vulnerabilities in the web user interface due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker who has a 'security' role can exploit this issue to inject HTML or JavaScript into the management session of other users, including the administrator.

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

Solution

Upgrade to Juniper ScreenOS version 6.3.0r24 or later. Alternatively, apply the workaround referenced in the vendor's advisory.
