dave b has discovered some vulnerabilities in pfSense, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "ifnum" and "ifname" parameters to graph.php in the web-based interface is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in an administrative user's browser session in context of an affected site.
The vulnerabilities are confirmed in version 1.2.3. Other versions may also be affected.
Solution: Do not browse untrusted web sites or follow links from untrusted sources while being logged-in to the application.
