CVE-2020-1706
An attacker with access to the running container can exploit this to modify /etc/passwd to add a user and escalate their privileges.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
It has been found that in openshift-enterprise version 3.11 and openshift-enterprise versions 4.1 up to, including 4.3, multiple containers modify the permissions of /etc/passwd to make them modifiable by users other than root. An attacker with access to the running container can exploit this to modify /etc/passwd to add a user and escalate their privileges. This CVE is specific to the openshift/apb-tools-container.
