Lifecycle Timeline
2DescriptionCVE.org
An out-of-bounds read vulnerability exists in the underlying operating system of AOS-CX that could lead to unauthenticated information disclosure by sending a specially crafted packet. Successful exploitation of this vulnerability results in the ability to disclose sensitive information from the underlying operating system.
AnalysisAI
Out-of-bounds read in the HPE AOS-CX network operating system allows adjacent unauthenticated attackers to disclose sensitive OS memory contents by sending a specially crafted packet. The flaw requires no credentials and no user interaction, but is constrained to same-segment network access (AV:A), limiting exposure to attackers who have already achieved a foothold on the target network or VLAN. …

Vulnerability AssessmentAI
| Exploitation | Attacker must be on the same Layer-2 network segment (broadcast domain, VLAN, or directly connected subnet) as the targeted AOS-CX interface - the Adjacent vector (AV:A) enforces this hard prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.5 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) is well-calibrated for this finding. … 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 patch specified in HPE Security Bulletin HPESBNW05134 (https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US), which addresses this vulnerability alongside the more severe co-disclosed RCE flaws in the same AOS-CX codebase - the upgrade path resolves all of them simultaneously. … Detailed patch versions, workarounds, and compensating controls in full report. |
