Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.
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.
