DescriptionCVE.org

An authenticated user with low-privileged access could submit crafted input through the web-based management interface to execute arbitrary commands on the underlying operating system.

AnalysisAI

OS command injection in HPE AOS-CX's web-based management interface allows any authenticated low-privileged user to execute arbitrary commands on the underlying switch operating system, achieving full device compromise. The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms the attack is fully remote, requires no user interaction, and demands only a minimal-privilege account - not administrative credentials. …
