More Details

We at MajorSecurity have discovered some vulnerabilities in Conpresso CMS v4.1.1, which can be exploited by
malicious people to conduct cross-site scripting attacks. Input passed via the "rubric" and "q" parameters to
mod_search/index.php 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 requires that "mod_search" is enabled in the application.
Solution

The vendor released a patch which fixes the issues. Download version 4.1.2 to make sure your conpresso cms
installation is secured. We would like to thank Thomas Walter of the Conpresso CMS development team for the
professional communication.
