Original Release date: 11 Feb 2014 | Last revised: 11 Feb 2014

Overview

DELL SonicWALL GMS/Analyzer/UMA version 7.1, and possibly earlier versions, contains a cross-site scripting (XSS) vulnerability. (CWE-79)

Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

DELL SonicWALL GMS/Analyzer/UMA version 7.1 contains a cross-site scripting vulnerability. The "node_id" parameter on the page "/sgms/mainPage?page=genNetwork&screenid=1002&manager=ScreenDisplayManager&level=1&node_id" is vulnerable.

Proof-of-Concept:
hxxps://{SONICWALL}/sgms/mainPage?page=genNetwork&screenid=1002&manager=ScreenDisplayManager&level=1&node_id=aaaaa"><script>alert(document.cookie);</script>&screenid=1002&unused=&help_url=&node_name=Instance View&unitType=1&searchBySonicwall=0

Impact

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user's browser session.

Solution

Apply an Update

Dell SonicWall has released version 7.1 SP2 or 7.2 to address this vulnerability. If you are unable to upgrade, please consider the following workaround.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the interface using stolen credentials from a blocked network location.
