Three Bitnami Helm charts mount Kubernetes Secrets under a predictable path (/opt/bitnami/*/secrets) that is located within the web server document root. In affected versions, this can lead to unauthenticated access to sensitive credentials via HTTP/S. A remote attacker could retrieve these secrets by accessing specific URLs if the application is exposed externally. The issue affects deployments using the default value of usePasswordFiles=true, which mounts secrets as files into the container filesystem.
The product makes files or directories accessible to unauthorized actors, even though they should not be.
Web servers, FTP servers, and similar servers may store a set of files underneath a “root” directory that is accessible to the server’s users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
