CVE-2023-34409: Percona Monitoring And Management

Critical severity, CVSS 9.8. EPSS: 1.3% chance of exploitation in the next 30 days.

In Percona Monitoring and Management (PMM) server 2.x before 2.37.1, the authenticate function in auth_server.go does not properly formalize and sanitize URL paths to reject path traversal attempts. This allows an unauthenticated remote user, when a crafted POST request is made against unauthenticated API routes, to access otherwise protected API routes leading to escalation of privileges and information disclosure.

Affected products

• Percona Monitoring And Management: from 2.0.0, before 2.37.1 (fixed in 2.37.1)
