Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.83% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Hewlett Packard Enterprise ArubaOS-Switch and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
There is a memory corruption vulnerability in AOS-S switches that could lead to unauthenticated remote code execution by sending specially crafted packets. Successful exploitation of these vulnerabilities results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
Remediation
To address the vulnerabilities described above for the affected release branches, it is recommended to upgrade the software to the following versions: - ArubaOS-Switch 16.11.xxxx: KB/WC/YA/YB/YC.16.11.0013 and above. - ArubaOS-Switch 16.10.xxxx: WB.16.10.0024 and above. - ArubaOS-Switch 16.08.xxxx: KB/WB/WC/YA/YB/YC.16.08.0027 and above. - ArubaOS-Switch 16.04.xxxx: KA/RA.16.04.0027 and above. - ArubaOS-Switch 15.xx.xxxx: A.15.16.0026 and above. Note: 16.10.xxxx:KB/WC/YA/YB/YC will not receive fixes for these vulnerabilities. Upgrading to KB/WC/YA/YB/YC.16.11.0013 and above will address these vulnerabilities. The software versions listed in the Resolution section are the supported branches as of the publication date of this advisory.

What, why and how

A memory corruption vulnerability in ArubaOS-Switch could lead to unauthenticated remote code execution by receiving specially crafted packets. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.

What

A memory corruption vulnerability in ArubaOS-Switch could lead to unauthenticated remote code execution by receiving specially crafted packets. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.

Why

A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-787 ↗

CWE-787: Out-of-bounds Write. The product writes data past the end, or before the beginning, of the intended buffer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CNoneConfidentiality impact: No direct loss is represented by this metric.INoneIntegrity impact: No direct loss is represented by this metric.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
