TinyPHPForum is prone to multiple directory traversal vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.

An attacker can exploit these vulnerabilities to retrieve arbitrary files from the vulnerable system in the context of the Web server process. Information obtained may aid in further attacks; other attacks are also possible.

These issues are reported to affect version 3.6; earlier versions may also be vulnerable.
