Two vulnerabilities have been reported in Gallery, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose sensitive information.
1) Some unspecified input passed via the "Add Image From Web" functionality isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability has been reported in versions 2.0 Alpha 1 through 2.0.1.
2) Some unspecified input passed to the zipcart module isn't properly verified, before it is used to view files. This can be exploited to disclose the content of arbitrary files from local resources.
Successful exploitation requires that the "zipcart" module is installed and enabled (not included in the minimal or typical packages, and not installed by default).
The vulnerability has been reported in versions 2.0 Alpha 3 through 2.0.1.
It has also been reported that the installer records certain information to a log file inside the Gallery data directory. However, the Gallery installer recommends that the data directory is placed outside of the web root.
