This is the first of a series of blog posts that deals with Plone migrations.
The hotfix for CVE-2011-0720 is now out for almost three months. Three months should be long enough for every responsible administrator for applying the hotfix.
However a quick check of 2300 Plone sites revealed that still 13% of the checked sites are running without protection.
13% = more than 300 unpatched and vulnerable sites. Of course there are many more Plone sites on the net but the number is likely representative for the other sites.
Every administrator or persons in charge for a public site should really check CVE-2011-0720 once again or give notice to the responsible persons for applying the patch.
Unpatched systems are bad for the security record of Plone and the public recognition as a secure CMS.
