[MajorSecurity SA-076]Conpresso CMS v4.1.1 - Cross site Scripting
Product: Conpresso CMS v4.1.1
Discovered by: David Vieira-Kurz of MajorSecurity
Conpresso CMS v4.1
Prior versions may also be vulnerable
"Conpresso CMS v4.1 is a web based content management system."
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 directly to the "q" and
"rubric" parameters in "index.php" is not properly sanitised before
being stored and 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 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.
