Reportedly, myPHPNuke does not adequately filter HTML code thus making it prone to cross-site scripting attacks. It is possible for a remote attacker to create a malicious link containing script code which will be executed in the browser of a legitimate user. All code will be executed within the context of the website running myPHPNuke. This issue may be exploited to steal cookie-based authentication credentials from legitimate users of the website running the vulnerable software.
