CVE-2023-20877Network attack vector

ReadOnly-user code execution and privilege escalation

Published May 12, 2023 · Updated Jan 27, 2025

Incorrect authorization in VMware Aria Operations before 8.12 allows remote authenticated users to execute code and escalate privileges. VMware has not published the affected component or the authorization check that incorrectly permits the operation. A ReadOnly account is sufficient, and successful exploitation grants higher privileges with confidentiality, integrity, and availability impact.
