Cloud Foundry Foundation
A regression introduced in the Staticfile buildpack causes the Staticfile.auth
configuration to be ignored when the Staticfile
file is not present in the application root. Applications containing a Staticfile.auth
file but not a Staticfile
had their basic auth turned off when an operator upgraded the Staticfile buildpack in the foundation to one of the vulnerable versions. Note that Staticfile applications without a Staticfile
are technically misconfigured, and will not successfully detect unless the Staticfile buildpack is explicitly specified.
OSS users are strongly encouraged to follow one of the mitigations below:
2017-04-10: Updated mitigation to apply to all apps using the Staticfile buildpack instead of just apps with detection
2017-04-10: Initial vulnerability report published
