Some vulnerabilities have been discovered in CPG Dragonfly CMS, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks.

1) Input passed via the "meta" parameter to index.php (when "name" is set to "coppermine" and "file" is set to "thumbnails") is not 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.

This vulnerability may be related to:
SA18940

2) Input passed via the URL to index.php (when "name" is set to "coppermine") is not 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.

Successful exploitation of this vulnerability requires "Enable debug mode" of the coppermine configuration to be enabled (enabled by default).

3) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. change the password of a super user when a logged-in super user visits a specially crafted web page.

The vulnerabilities are confirmed in version 9.3.3.0. Other versions may also be affected.

Solution
Update to version 9.3.4.0, which fixes vulnerabilities #1 and #2.
