Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.52% 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: 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.

Summary
A vulnerability in the ArubaOS-Switch web management interface could allow an unauthenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface provided certain configuration options are present. A successful exploit could allow an attacker to execute arbitrary script code in a victim’s browser in the context of the affected interface.
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 vulnerability in the ArubaOS-Switch web management interface could allow an unauthenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface provided certain configuration options are present. A successful exploit could allow an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface.

What

A vulnerability in the ArubaOS-Switch web management interface could allow an unauthenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface provided certain configuration options are present. A successful exploit could allow an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface.

Why

Attacker-controlled content can reach a browser as executable script without sufficient output encoding or sanitisation.

How

An attacker operating through a network path may attempt exploitation without authentication after a user interaction. 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 Input During Web Page Generation ('Cross-site Scripting') → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
High: exploitation depends on specific conditions
Security boundary
Changed: exploitation can affect a different security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-79 ↗

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

?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.
