Software: WordPress Click to Copy Grab Box Plugin 0.x

Henri Salo has discovered two vulnerabilities in the Click to Copy Grab Box plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed via the "id" parameter to wp-content/plugins/click-to-copy-grab-box/lib/ZeroClipboard.swf and wp-content/plugins/click-to-copy-grab-box/lib/ZeroClipboard10.swf 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.

The vulnerabilities are confirmed in version 0.1.1. Other versions may also be affected.

No official solution is currently available.
