CVE-2023-20887Known exploitationPublic exploitNetwork attack vector

Unauthenticated root command execution via unsanitized nodeId

Published Jun 7, 2023 · Updated Oct 21, 2025

OS command injection in VMware Aria Operations for Networks 6.2.0 through 6.10.0 allows remote attackers to execute commands as root. The createSupportBundle handler passes its nodeId field unsanitized into a shell command after an nginx rewrite exposes its local Thrift endpoint. Network access to the appliance HTTPS service is sufficient; successful exploitation grants root control over the appliance.
