phpCOIN 1.2.1 - 'mod' Local File Inclusion

source: https://www.securityfocus.com/bid/38576/info

phpCOIN is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to obtain potentially sensitive information and execute arbitrary local scripts in the context of the webserver process. This may allow the attacker to compromise the application and the underlying computer; other attacks are also possible.

phpCOIN 1.2.1 is vulnerable; other versions may also be affected.
