Janek Vind has reported multiple vulnerabilities in the Coppermine Photo Gallery module for phpNuke/postNuke, allowing malicious people to compromise a vulnerable system or conduct Cross Site Scripting attacks.
1) If error messages hasn't been turned off in PHP, various scripts will return error messages if the scripts are accessed directly. This can be exploited to reveal the installation path.
2) Input passed to the "CPG_URL" parameter in the "menu.inc.php" script isn't properly verified before it is returned to the user. This can be exploited to execute arbitrary HTML or script code in a user's browser session in context of an affected site by tricking the user into visiting a malicious website or follow a specially crafted link.
3) Various scripts fail to verify certain parameters before using them to include files. This can be exploited to include arbitrary script code from external and local resources.
