Multiple vulnerabilities have been reported in pfSense, which can be exploited by malicious people to conduct cross-site request forgery and cross-site scripting attacks and cause a DoS (Denial of Service).
For more information:
SA63113
1) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. delete arbitrary files when a logged-in user visits a specially crafted web page.
2) Input passed via multiple parameters to multiple scripts is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
