Multiple vulnerabilities have been reported in Citrix Licensing, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks and cause a DoS (Denial of Service).
1) Certain unspecified input passed to the administration console 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.
2) The application's web interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to create an arbitrary user with administrative privileges if a logged-in administrator visits a malicious web site.
3) An error in the administration console can be exploited to cause a crash via an overly long string appended to the URL.
The vulnerabilities are reported in versions prior to 11.10.
