AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Adjacent-network CLI access before authentication justifies AV:A and PR:N; format string leading to privileged OS RCE warrants full C:H/I:H/A:H with unchanged scope.

2DescriptionCVE.org
A format string vulnerability exists in the command line interface of AOS-CX that could lead to unauthenticated remote code execution. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
AnalysisAI
Format string exploitation in the HPE AOS-CX command line interface enables unauthenticated, adjacent-network attackers to execute arbitrary code with elevated privileges on the underlying operating system. All AOS-CX versions are affected per the wildcard CPE, and the vulnerability is disclosed alongside three other critical AOS-CX flaws in the same HPE bulletin (HPESBNW05134), suggesting coordinated security research. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be positioned on the same Layer 2 network segment or management VLAN as the target AOS-CX switch - full internet-based exploitation is not possible without a prior network foothold. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects a high-severity, low-complexity, unauthenticated threat bounded by the adjacent-network attack vector. … 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 patched AOS-CX firmware version specified in HPE Security Bulletin HPESBNW05134 at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US; this bulletin also addresses CVE-2026-73749, CVE-2026-73766, and CVE-2026-73778, so a single patch cycle resolves all four. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all HPE AOS-CX deployments and immediately restrict CLI network access via firewall rules to authorized administration subnets only; disable CLI access via alternative management interfaces if available. …
