OITSEC has been seeing reports of Wordpress and other sites being
compromised and reconfigured to serve up exploit code to unsuspecting site
visitors.  In some cases, compromised sites were configured in such a way
that they only served exploit code to certain clients, e.g., responses were
based on things like the client's browser identification string.  This in
itself is not new, nor are weaknesses in Wordpress.

However, in one case, Wordpress and the platform on which it was running
was completely patched and had no known vulnerabilities.  What apparently
happened was the admins were very diligent in ensuring the OS, web server,
and Wordpress were completely patched... but neglected to check for
vulnerable plug-ins/add-ons.  If you're running a similar CMS that allows
plug-ins, those plug-ins needed to be added to your list of

Another weakness in some of the CMSes is themes.  Code included in themes
added to the CMS may not be robust, and may introduce interesting
"features" that are later used by someone else to help you "maintain" your

Bottom line:  If you're running a CMS, please be careful to check that
*all* the sources for features in or added to the CMS are proactively
securing their code.
