Title: Japanese PHP Gallery Hosting Arbitrary File Upload Vulnerability
Severity: HIGH
Description:
Japanese PHP Gallery Hosting is a web-based image gallery.
Japanese PHP Gallery Hosting is prone to an arbitrary-file-upload vulnerability because it fails to adequately sanitize user-supplied input.
This issue affects the 'mode' parameter of the '/upload/upload.php' script when it handles specially crafted filenames.
NOTE: Reports suggest that 'Open directory mode' must be enabled for this issue to occur, but this has not been confirmed.
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.
