Aria-Security has reported some vulnerabilities in cPanel, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site scripting and cross-site request forgery attacks.
1) Input passed to the "dir" parameter in files/seldir.html and htaccess/newuser.html 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 affected site.
2) Input passed to the "user" parameter in htaccess/newuser.html is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in an administrative user's browser session in context of an affected site.
3) An error exists due to the application allowing users to perform certain actions via HTTP requests without performing any validity checks to verify the user's request. This can e.g. be exploited conduct script insertion attacks in combination with vulnerability #2.
The vulnerabilities are reported in version 10. Other versions may also be affected.
