- Summary
- CloudNativePG: Cleartext role passwords recorded in pg_stat_statements allow privileged tenant roles to recover the PostgreSQL superuser credential and achieve RCE in the database pod
- Details
-
CloudNativePG is a platform designed to manage PostgreSQL databases within Kubernetes environments. Prior to 1.28.4 and 1.29.2, CloudNativePG embedded cleartext role passwords in
ALTER ROLEandCREATE ROLEstatements generated by SetUserPassword in pkg/management/postgres/utils/roles.go and appendPasswordOption in internal/management/controller/roles/postgres.go. When pgstatstatements was preloaded with trackutility enabled and an untrusted tenant held pgmonitor or pgreadall_stats, the tenant could recover platform-managed superuser or application-owner passwords, reconnect through enabled superuser TCP access, and execute operating system commands in the database pod withCOPY ... FROM PROGRAM. Clusters using SCRAM-SHA-256 verifiers in managed-role Secrets were not affected. This issue is fixed in versions 1.28.4, 1.29.2, and 1.30.0. - Database specific
