CVE-2022-1677
This malformed entry can match any arbitrary hostname, or all hostnames in the cluster, and direct traffic to an arbitrary application within the cluster, including one under attacker control.
Does this matter?
Lower severity and a low EPSS score (0.58%). Track it; it rarely justifies an emergency change on its own.
Description
In OpenShift Container Platform, a user with permissions to create or modify Routes can craft a payload that inserts a malformed entry into one of the cluster router's HAProxy configuration files. This malformed entry can match any arbitrary hostname, or all hostnames in the cluster, and direct traffic to an arbitrary application within the cluster, including one under attacker control.
