CVE-2015-6927
3.6 · LOWOverview
CVE-2015-6927 is a low-severity vulnerability affecting openvz vzctl. It was published on September 28, 2015 and has a CVSS 2.0 base score of 3.6 (LOW).
This vulnerability has a CVSS 2.0 base score of 3.6, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
vzctl before 4.9.4 determines the virtual environment (VE) layout based on the presence of root.hdd/DiskDescriptor.xml in the VE private directory, which allows local simfs container (CT) root users to change the root password for arbitrary ploop containers, as demonstrated by a symlink attack on the ploop container root.hdd file and then access a control panel.
Remediation
Check the references section for vendor advisories and patches from openvz. Update vzctl to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
