Detailsinfo

A vulnerability was found in VMware Bitnami up to 4.6.0-debian-12-r7/15.x. It has been declared as critical. This vulnerability affects some unknown functionality. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The bitnami/pgpool Docker image, and the bitnami/postgres-ha k8s chart, under default configurations, comes with an 'repmgr' user that allows unauthenticated access to the database inside the cluster. The PGPOOL_SR_CHECK_USER is the user that Pgpool itself uses to perform streaming replication checks against nodes, and should not be at trust level. This allows to log into a PostgreSQL database using the repgmr user without authentication. If Pgpool is exposed externally, a potential attacker could use this user to get access to the service. This is also present within the bitnami/postgres-ha Kubernetes Helm chart.

The advisory is available at github.com. This vulnerability was named CVE-2025-22248 since 01/02/2025. The exploitation appears to be easy. The attack can only be initiated within the local network. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.
