The vendor explicitly identifies these products as affected by this CVE.

  • SCALANCE W1750D
Summary
Authenticated command injection vulnerabilities exist in the ArubaOS command line interface. Successful exploitation of these vulnerabilities result in the ability to execute arbitrary commands as a privileged user on the underlying operating system. This allows an attacker to fully compromise the underlying operating system on the device running ArubaOS.
Remediation
Update to V8.7.1.3 or later version

What, why and how

A remote arbitrary command execution vulnerability was discovered in Aruba SD-WAN Software and Gateways; Aruba Operating System Software version(s): Prior to 8.6.0.4-2.2.0.4; Prior to 8.7.1.4, 8.6.0.9, 8.5.0.13, 8.3.0.16, 6.5.4.20, 6.4.4.25. Aruba has released patches for Aruba SD-WAN Software and Gateways and ArubaOS that address this security vulnerability.

What

A remote arbitrary command execution vulnerability was discovered in Aruba SD-WAN Software and Gateways; Aruba Operating System Software version(s): Prior to 8.6.0.4-2.2.0.4; Prior to 8.7.1.4, 8.6.0.9, 8.5.0.13, 8.3.0.16, 6.5.4.20, 6.4.4.25. Aruba has released patches for Aruba SD-WAN Software and Gateways and ArubaOS that address this security vulnerability.

Why

Untrusted input reaches a command interpreter without sufficient validation or separation from command syntax.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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 Neutralization of Special Elements used in a Command ('Command Injection') → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
High: elevated access is required
User interaction
None
Attack complexity
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-77 ↗

CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'). The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

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
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
