DescriptionCVE.org

A vulnerability exists in a management component that could allow an unauthenticated adjacent attacker to execute arbitrary commands. Successful exploitation could result in remote execution of arbitrary commands in the context of the affected utility.

AnalysisAI

Unauthenticated command execution in HPE AOS-CX's management component allows an attacker with adjacent network access to run arbitrary commands in the context of the affected utility. The vulnerability requires high attack complexity (AV:A/AC:H) but no credentials, making it exploitable by a well-positioned attacker on the same network segment without authentication. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to be network-adjacent (same Layer-2 segment or VLAN) to the management interface of an affected HPE AOS-CX device - remote internet-based exploitation is not possible per AV:A. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 7.1 score reflects a meaningful but constrained threat profile. … 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 the HPE security bulletin (https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US) for patched AOS-CX firmware versions and upgrade instructions, as no specific fix version is independently confirmed from the provided data. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all HPE AOS-CX management deployments in your production environment and document their network connectivity, criticality, and current access controls. …
