The remote host is running the Gallery web-based photo album.

There is a flaw in this version which may allow an attacker to bypass
the authentication mecanism of this software by making requests including
the options GALLERY_EMBEDDED_INSIDE and GALLERY_EMBEDDED_INSIDE_TYPE.

Solution : Upgrade to Gallery 1.4.3p2 or newer
Risk factor : Low";
