Matteo Carli has reported some vulnerabilities in cPanel, which can be exploited by malicious people to conduct cross-site scripting and cross-site request forgery attacks.

1) Input passed to the "issue" parameter in scripts2/knowlegebase, "user" in scripts2/changeip, and "search" in scripts2/listaccts 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.

NOTE: Other parameters are reportedly also affected.

2) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to e.g. add users, change passwords, suspend accounts, or restart services or the server by enticing a logged-in user to visit a malicious web site.

The vulnerabilities are reported in versions prior to 11.18.4-23888 and 11.22.2-23808.

Solution
Update to version 11.18.4-23888 or 11.22.2-23808.
