Description Paramvir jindal 2020-03-26 14:16:47 UTC
It has been found that 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/redhat-sso-7 container.
