DescriptionCVE.org

Exploitation through affected command-line operations could allow an authenticated low-privileged user to execute arbitrary commands as a privileged user on the underlying operating system.

AnalysisAI

Privilege escalation in HPE AOS-CX allows an authenticated low-privileged user to execute arbitrary commands with the privileges of a higher-privileged or root-level account on the underlying operating system. The vulnerability is triggered through specific command-line operations within the AOS-CX CLI environment, making it exploitable over the network by any user with basic CLI credentials. …

Vulnerability AssessmentAI

Exploitation Exploitation requires: (1) a valid low-privileged user account on the AOS-CX device with CLI access; (2) network reachability to the switch management interface (SSH or equivalent). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately reflects a high-severity, low-complexity network attack requiring only a low-privileged credential - realistic in environments where read-only or operator-tier network accounts are provisioned. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Consult and apply the patch detailed in HPE Security Bulletin HPESBNW05134 at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US - an exact fixed AOS-CX firmware version is not available in the provided data and must be obtained directly from the bulletin. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all HPE AOS-CX switches; immediately restrict CLI access to only explicitly authorized administrators and disable remote CLI access where operationally feasible; ensure strong credential hygiene for remaining CLI users. …
