Multiple Input Validation Vulnerabilities

Multiple input validation vulnerabilities in FlatNuke allow an attacker 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. This can be done by supplying malicious input to vulnerable parameters such as 'border' and 'back' in the help.php script.

Mitigation:

Input validation should be performed to ensure that untrusted input is not used to generate Web content or load scripts.

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.
