DescriptionCVE.org

Denial-of-service vulnerabilities exist in the command line interface of AOS-CX. Successful exploitation could allow an authenticated user to disrupt the normal operation of a vulnerable system.

AnalysisAI

Denial-of-service conditions in HPE AOS-CX's command line interface allow a low-privileged authenticated user with network access to disrupt normal system operation. Part of the broader HPE advisory hpesbnw05134 addressing multiple AOS-CX vulnerabilities, this issue targets the CLI layer - accessible over SSH - but requires high attack complexity to successfully trigger. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated low-privilege account with SSH (or equivalent CLI) access to the AOS-CX device over the network (AV:N, PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 5.3 medium score reflects a meaningful but bounded risk: AV:N/PR:L means any authenticated CLI user reachable over the network can attempt exploitation, but AC:H constrains the threat to adversaries who can satisfy specific, non-obvious preconditions. … 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 Administrators should consult HPE advisory hpesbnw05134 at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US for the specific patched AOS-CX software versions and apply the vendor-recommended updates. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
