Description


rgod has discovered some vulnerabilities in Flatnuke, which can be exploited by malicious people to disclose certain sensitive information, perform certain actions with escalated privileges, or to compromise a vulnerable system.

1) Input passed to the "userlang" parameter in header.php is not properly verified before being used to include files. This can be exploited to include files from local resources.

2) Input passed to the "file_da_canc" parameter in sections/none_Sondaggio/Vecchi_sondaggi/sections.php is not properly verified before being used. In combination with #1 this can be exploited to delete arbitrary files with privileges of the web server.

3) An input validation error exists in the authentication process when checking the "myforum" cookie parameter. This can e.g be exploited to upload and execute arbitrary PHP files.

The vulnerabilities have been confirmed in version 2.5.8. Other versions may also be affected.


Solution:
Edit the source code to ensure that input is properly verified.
