CVE-2023-39266
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA stored cross-site scripting vulnerability exists in the ArubaOS-Switch web management interface. An unauthenticated remote attacker can inject malicious script code into the interface, which is then stored and executed when legitimate users access the affected content. Exploitation is conditional on specific configuration options being enabled on the device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine the ArubaOS-Switch versionAccess the device CLI and run 'show version' or use the web management interface to view the system information page showing the OS versionAffected if The installed version falls within any of these ranges: < a.15.16.0026; >= 16.01.0000 and < 16.04.0027; >= 16.05.0000 and < 16.08.0027; >= 16.10.0001 and < 16.10.0024; >= 16.11.0001 and < 16.11.0013
-
Verify the web management interface is enabledIn the CLI, run 'show web-management' or check the web interface configuration in the device management settingsAffected if The web management interface (HTTP or HTTPS) is currently enabled on the device
-
Check for unauthenticated web access configurationIn the CLI, run 'show running-config | include web-management' or examine the web management security settings to see if unauthenticated access or specific management features are configuredAffected if The device is configured to allow unauthenticated access to the web management interface or has specific configuration options that permit the vulnerability to be exploited
A device is affected if it runs a vulnerable ArubaOS-Switch version AND has the web management interface enabled with configuration options that permit the exploit path.

Apply the vendor patch from Aruba and review/adjust the configuration options that enable this vulnerability. Consider disabling the web management interface if not required, or implementing additional access controls.
a.15.16.0026 (for 15.x branch), 16.04.0027 (for 16.01.x branch), 16.08.0027 (for 16.05.x branch), or 16.10.0024 (for 16.10.x branch)
- 1. Identify the currently installed ArubaOS-Switch version by checking the system information in the web management interface or via CLI with 'show version'.
- 2. Determine which version branch your current installation belongs to (15.x, 16.01.x, 16.05.x, or 16.10.x).
- 3. For ArubaOS 15.x versions: Upgrade to version a.15.16.0026 or later.
- 4. For ArubaOS 16.01.x versions: Upgrade to version 16.04.0027 or later.
- 5. For ArubaOS 16.05.x versions: Upgrade to version 16.08.0027 or later.
- 6. For ArubaOS 16.10.x versions: Upgrade to version 16.10.0024 or later.
- 7. Download the appropriate firmware from the official Aruba support portal at https://asp.arubanetworks.com/.
- 8. Upload and install the new firmware via the web management interface or CLI following Aruba's standard upgrade procedures.
