Discussion
Free Simple CMS Local File Include and Cross Site Scripting Vulnerabilities
Free Simple CMS is prone to a local file-include vulnerability and multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker can exploit the local file-include vulnerability using directory-traversal strings to view and execute local files within the context of the affected application. Information harvested may aid in further attacks.
The attacker may leverage the cross-site scripting issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.
Free Simple CMS 1.0 is vulnerable; other versions may also be affected.
