Description

Cloud foundry team found that the kernel audit logging is enabled on some components due to which various lifecycle workflows in the platform that use admin or service credentials in invocations of binaries are picked up by the audit logging, which record arguments passed to binary invocations that access the filesystem. A malicious user may use these credentials to deploy apps on CF instance.
