CVE-2024-29990Network attack vector

Unauthenticated privilege escalation via undisclosed access control

Published Apr 9, 2024 · Updated May 3, 2025

Improper access control in Microsoft Azure Kubernetes Service before 0.3.4 allows remote attackers to elevate privileges over a network. Microsoft has not published the affected component, request path, or improper access-control operation beyond the CWE-284 classification. Exploitation requires a high-complexity network condition but no prior privileges or user interaction, and successful compromise crosses a security boundary and affects protected data and service operation.
