An internal security audit turned up 3 separate vulnerabilities. These
are all resolved in Gallery 2.0.2, released on 11/28/2005 and available
1. The installer records information in an install log that is stored
in the gallery data directory. An attacker can discover the location of
this directory and read this file to discover information about the
Gallery installation. The Gallery installer recommends that you put the
gallery data directory outside of your webserver's document root, and
allows you to name this directory anything that you choose, however if
the user may choose to put it in an obvious place. Site administrators
can delete this file by hand to disarm the flaw.
2. The "Add Image From Web" feature is vulnerable to executing
exploited via XSS that way. This requires the attacker to trick the a
Gallery user into loading images from that page.
3. The zipcart module, if installed and activated can be used to view
any files on the webserver that are visible to the webserver user.
Gallery is delivered in 4 flavors (minimal, typical, full, developer).
The zipcart module is not included in the minimal or typical packages.
It is also not installed by default. It must be manually selected for
install and activation by the Gallery site administrator. Site
administrators can deactivate this module to disarm the flaw.
