Multiple input validation vulnerabilities reportedly affect FlatNuke. These issues are due to a failure of the application to properly sanitize user-supplied input prior to using it in application-critical actions such as generating Web content or loading scripts.

An attacker may leverage these issues to execute arbitrary PHP code, execute client-side script code in the browsers of unsuspecting users through cross-site scripting attacks, and gain access to sensitive information. Other attacks are also possible.
