Mavituna Security has discovered a vulnerability in Exponent CMS, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "src" parameter to index.php (when "controller" is set to "expTag" and "action" is set to "show") is not properly sanitised framework/modules/core/views/expTag/show.tpl 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 is confirmed in version 2.0.6. Prior versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised.
