Lifecycle Timeline
2DescriptionCVE.org
An issue was discovered in Percona PMM Server (OVA) before 3.0.0-1.ova. The default service account credentials can lead to SSH access, use of Sudo to root, and sensitive data exposure. This is fixed in PMM2 2.42.0-1.ova, 2.43.0-1.ova, 2.43.1-1.ova, 2.43.2-1.ova, and 2.44.0-1.ova and in PMM3 3.0.0-1.ova and later.
AnalysisAI
Percona PMM Server OVA images ship with default service account credentials that grant SSH access and sudo to root, exposing all monitoring data and managed database credentials. The scope change reflects that compromising the monitoring server gives access to all monitored infrastructure.
Technical ContextAI
The OVA image includes a service account with hardcoded default credentials (CWE-1393). An attacker who discovers an exposed PMM Server can SSH in with default credentials and immediately sudo to root. Since PMM stores credentials for all monitored databases, this is a pivot point to the entire database fleet.
Affected ProductsAI
Percona PMM Server OVA before PMM2 2.42.0-1.ova and PMM3 3.0.0-1.ova
RemediationAI
Upgrade to PMM2 >= 2.42.0 or PMM3 >= 3.0.0. Change all default credentials immediately. Never expose PMM Server to the internet. Rotate all monitored database credentials if exposure is suspected.
