Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.87% 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 (HPE) AOS-CX 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: Within 30 daysRemediation target: Within 180 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.

  • AOS-CX
Summary
An authenticated path traversal vulnerability exists in AOS-CX. Successful exploitation of this vulnerability allows an attacker to copy arbitrary files to a user readable location from the command line interface of the underlying operating system, which could lead to remote code execution. NOTE: AOS-CX 10.10.xxxx is not impacted.
Remediation
To address the vulnerabilities described above in the affected software branches, it is recommended to upgrade HPE Networking AOS-CX to one of the following versions (as applicable): - AOS-CX 10.18.xxxx: AOS-CX 10.18.0001 and above - AOS-CX 10.17.xxxx: AOS-CX 10.17.1021 and above - AOS-CX 10.16.xxxx: AOS-CX 10.16.1050 and above - AOS-CX 10.13.xxxx: AOS-CX 10.13.1180 and above Software versions with resolution/fixes for the vulnerabilities covered above can be downloaded from the HPE Networking Support Portal at https://networkingsupport.hpe.com/home/ NOTE: CVE-2026-63454 is resolved in AOS-CX 10.13.1190. Customers running this software branch that are unable to upgrade to a newer software branch are advised to use the available workaround until this resolved version becomes publicly available. HPE Aruba Networking does not evaluate or patch software branches that have reached their End of Maintenance (EoM) milestone.

What, why and how

An authenticated path traversal vulnerability exists in AOS-CX. Successful exploitation of this vulnerability allows an attacker to copy arbitrary files to a user readable location from the command line interface of the underlying operating system, which could lead to remote code execution.

What

An authenticated path traversal vulnerability exists in AOS-CX. Successful exploitation of this vulnerability allows an attacker to copy arbitrary files to a user readable location from the command line interface of the underlying operating system, which could lead to remote code execution.

Why

Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.

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
a network path → Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') → execute code or commands in the affected security context
Attack surface
Network
Privileges required
High: elevated access is required

Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-22 ↗

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

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.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.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.
