CVE-2026-79846 Hewlett Packard Enterprise (HPE) CVE debrief

Who should care

System administrators and security teams responsible for ArubaOS (AOS) deployments should assess exposure and prioritize patching for versions 8.10.0.0 through 8.10.0.23 and 8.13.0.0 through 8.13.3.0.

Why it matters

CVE-2026-79846 is a critical unauthenticated command injection vulnerability in AOS-8, allowing an attacker to execute arbitrary commands on the underlying operating system. System administrators and security teams should assess exposure, prioritize patching, and implement compensating controls to limit potential attack surfaces.

• Verify patch deployment for AOS-8 versions 8.10.0.0 through 8.10.0.23 and 8.13.0.0 through 8.13.3.0
• Assess network segmentation and access controls to limit potential attack surfaces
• Monitor for potential exploitation attempts on AOS-8 interfaces

Technical summary

CVE-2026-79846 is a critical unauthenticated command injection vulnerability in AOS-8. The vulnerability exists in the affected interface of AOS-8, allowing an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.
