Vulnerability Note VU#960468

HP Arcsight Logger and Connector appliances cross-site scripting vulnerability

Original Release date: 06 Aug 2012 | Last revised: 06 Aug 2012

Overview

HP's Arcsight Connector appliance v6.2.0.6244.0 and Arcsight Logger appliance
v5.2.0.6288.0 (and possibly other versions) contain a file import facility
which is vulnerable to cross-site scripting (XSS).

Description

The supplied facility for importing host data from a file (System Admin Tab |
Network | Hosts | Import from Local File) to the HP Arcsight Connector or HP
Arcsight Logger appliances fail to sanitize input for cross-site scripting
attacks. An attacker with write access to the file that will be imported can
add javascript code into the file.  This code will be run in the security
context of the appliance administrative web GUI when the file is imported.

Impact

A remote attacker may, by luring a user into importing a malicious host file,
be able to disclose sensitive information, steal user cookies, or escalate
privileges.

Solution

We are currently unaware of a practical solution to this problem.

Do not import host file from untrusted sources

Attackers must deliver a malicious host file to, or modify an existing file on,
a vulnerable system in order to take advantage of this vulnerability. By only
accessing host files, which cannot be modified by unprivileged users, from
known and trusted sources the chances of exploitation are reduced.
