Hi Aslan - are you referring to the CloudStack vulnerability announcement related to authentication bypass we announced in April? (CVE 2013-2756)
If so, to fix the issue you need to upgrade to CloudStack 4.0.2. Do note there's issues with Ceph on ACS 4.0.2, so if you are using Ceph we'll have to figure out another way to fix for you.
