Description:
frog-m@n has reported two vulnerabilities in Nuked-KlaN, allowing malicious people to include arbitrary scripts and corrupt the configuration file.

User input passed to the "user_langue" parameter in "index.php" is not properly verified before being used to include files. This can be exploited to include arbitrary scripts and files from local resources.

It is possible to overwrite globally defined variables defined in the configuration file. This can be exploited to cause unexpected behaviour and potentially corrupt the configuration file.

This has been reported to affect version 1.5b and prior.

Solution:
Edit the source code to ensure that input passed to the "user_langue" parameter is properly sanitised.
