Comment on Disclosure of sensitive credentials and configuration in containerized deployments - ownCloud
sphericth0r@kbin.social 6 months agoIt's probably best to look at what the devops industry is embracing, environment variables are as secure as any of the alternatives but poor implementations will always introduce attack vectors. Secret management stores require you to authenticate, which requires you to store the credential for it somewhere - no matter what there's no way to secure an insecure implementation of secrets access

They are not as secure, because there are less controls for ENV variables. Anybody in the same PID namespaces can cat /proc/PID/environ and read them. For files (say, config file) you can use mount namespaces and the regular file permissions to restrict access.
Of course you can mess up a secret implementation, but a chmod’d 600 file from another user requires some sort of arbitrary read vulnerability or privilege escalation (assuming another application on the same host is compromised, for example). If you get low-privileged access to the host, chances are you can dump the ENV for all processes.
Security-wise, ENV variables are worse compared to just a mounted config file, for example.
