CRITICAL 9.8

DescriptionCVE.org

Multiple vulnerabilities exist in a daemon of AOS-CX that may allow for improper processing of malformed input. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted packets to the affected service. Successful exploitation could result in remote code execution with elevated privileges.

AnalysisAI

Remote code execution in HPE Aruba Networking AOS-CX (the network operating system running on Aruba CX switches) allows an unauthenticated remote attacker to run arbitrary code with elevated privileges by sending specially crafted packets to a vulnerable daemon. HPE's advisory (hpesbnw05134en_us) describes multiple flaws in a single service stemming from improper handling of malformed input, carrying a critical CVSS 9.8. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network reachability to the specific AOS-CX daemon that improperly parses malformed input on an affected Aruba CX switch; the attacker must be able to deliver crafted packets to that service. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment All available signals point to genuine high priority: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H describes network-reachable, low-complexity, unauthenticated exploitation with full confidentiality, integrity, and availability impact, and the description independently corroborates unauthenticated remote RCE with elevated privileges. … 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 Apply the fixed AOS-CX firmware identified in HPE security bulletin hpesbnw05134en_us (https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US); no exact fixed version is present in the provided data, so pull the precise upgrade target from that advisory rather than relying on an invented version. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within the next 24 hours, identify and inventory all HPE Aruba CX switches running AOS-CX in your environment and immediately restrict management interface access through network ACLs and VLAN isolation to prevent unauthorized access. …
