Vulnerability Note VU#122054

HP ArcSight Connector Appliance XSS vulnerability

Overview

ArcSight Connector Appliance v6.0.0.60023.2, and possibly previous versions, 
contains a module which is vulnerable to cross site scripting (XSS).

I. Description

Windows Event Log SmartConnector, a component of ArcSight Connector Appliance 
v6.0.0.60023.2 does not sanitize all input fields. As a result, cross site 
scripting (XSS) attacks can be conducted. An exportable report from the Windows 
Event Log SmartConnector for table parameters contains a drop-down selection 
field for "Microsoft OS Version". In some cases, this exported report is 
world-writeable with a default name. In the exported file an attacker can 
inject javascript code that will be run after the file is imported and the
table parameters section is accessed for editing again.

For example, the following javascript code can be injected into the "Windows 
XP" variable of the exported file:

...,"Windows XP<script> alert('XSS')</script>","en_US"

II. Impact

An attacker with access to the ArcSight Connector Appliance can conduct a cross 
site scripting attack, which could be used to result in information leakage, 
privilege escalation, and/or denial of service.

III. Solution

Apply an Update

ArcSight Connector Appliance version 6.1 addresses this vulnerability.
