------------------------------------------------------------------------
Han Sahin, September 2014

Abstract
------------------------------------------------------------------------
It has been found that Websense Reporting is affected by multiple
Cross-Site Scripting issues. Cross-Site Scripting allows an attacker to
perform a wide variety of actions, such as stealing the victim's session
token or login credentials, performing arbitrary actions on the victim's
behalf, and logging their keystrokes.

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
This issue was discovered on Websense Triton v7.8.3 and Websense
appliance modules V-Series v7.7. Other versions may be affected as well.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
Websense released hotfix 02 for Websense Triton v7.8.4 in which this
issue is fixed. More information about this hotfix can be found at the

One example of a vulnerable request parameter is the col. Its value is copied into the value of an HTML tag attribute; encapsulated in double quotation marks. The value echoed unmodified (without output encoding) in the application's response. This vulnerability can be reproduced using the following steps:

- login into Admin GUI;
- open the proof of concept below;
- hover over 'Risk Class' in left corner.

An attacker must trick victims into opening the attacker's specially crafted link. This is for example possible by sending a victim a link in an email or instant message. Once a victim opens the specially crafted link, arbitrary client-side scripting code will be executed in the victim's browser. The attacker-supplied code can perform a wide variety of actions, such as stealing the victim's session tokens or login credentials, performing arbitrary actions on their behalf, logging their keystrokes.
