Coppermine Photo Gallery 1.4.21 Cross-Site Scripting

Author: Gerendi Sandor Attila

Date: April 29, 2009

Package: Coppermine Photo Gallery (cpg1.4.21)

Product homepage: http://coppermine-gallery.net/

Versions Affected: v.1.4.21 (older versions are also affected)

Advisory: http://gsasec.blogspot.com/2009/04/coppermine-photo-gallery-1421-cross.h
tml

Severity: Medium

Input passed to the 'css' parameter from '/docs/showdoc.php' is not sanitized before it is 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.

Example:

http://somehost/docs/showdoc.php?css=1>">alert(123)%3B

The vendor already released a security release which fixes the issue, read at: http://forum.coppermine-gallery.net/index.php/topic,59247.0.html

(cpg1.4.22 Security release - upgrade mandatory)
