Janek Vind has reported multiple vulnerabilities in PHP-Nuke, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose path information, and cause a DoS (Denial of Service).

1) Input passed to various parameters in the "Reviews", "Encyclopedia", and "Faq" modules isn't 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 a vulnerable site.

2) An input validation error within the "Reviews" module can be exploited to manipulate SQL queries by passing arbitrary SQL code to the "order" parameter.

3) Path information can be disclosed in error pages by passing invalid input to the "preview_review()" function in the "Reviews" module.

4) An input validation error within the score subsystem of the "Reviews" module can be exploited to manipulate scores, disclose path information, and ultimately cause the server to consume excessive amounts of CPU and memory resources.

The vulnerabilities have been reported in versions 6.x through 7.3.
