RCE in the underlying OS of Aruba AOS-10 — a widely deployed enterprise network OS. Exploitation yields privileged OS command execution and full device compromise, risking enterprise network infrastructure.
CVE-2026-79877
Unauthenticated adjacent RCE in Aruba AOS-10 OS allowing full device compromise
Is CVE-2026-79877 being exploited?
Not confirmed. CVE-2026-79877 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.37% probability of exploitation in the next 30 days.
How severe is CVE-2026-79877?
CVE-2026-79877 is rated High with a CVSS score of 8.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-79877?
Not known from our data. No patch reference has been recorded for CVE-2026-79877, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2026-79877 affect?
CVE-2026-79877 affects HPE Aruba AOS-10 (underlying OS on controllers/switches/APs). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-79877?
Apply vendor guidance, isolate affected devices from adjacent networks, patch when vendor releases fix.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Adjacent unauthenticated attacker can execute arbitrary privileged OS commands, leading to full device compromise and potential network control.
