Remediation
Red Hat statement
OpenShift Container Platform allows for various types of "source clone secrets" to be defined in order to permit building from non-public git repositories. When using ssh key authentication, the server host key checking function is disabled. An attacker with the ability to redirect the network traffic and perform a "man in the middle" attack will be able to redirect the build job to use arbitrary content of their choosing. Note that the same flaw (non-verification of remote server) is present when using HTTP, or when using HTTPS with TLS verification manually disabled.
Red Hat mitigation
Use only methods (such as HTTPS with TLS verification) that enable the identity of the remote repository to be validated.
