CVE-2026-23827
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 heap-based buffer overflow vulnerability exists in a Network management service of AOS-8 and AOS-10 that could allow an unauthenticated remote attacker to achieve remote code execution. Successful exploitation could allow an unauthenticated attacker to execute arbitrary code as a privileged user on the underlying operating system, potentially leading to a system compromise. Exploitation may also result in a denial-of-service (DoS) condition affecting the impacted system process.
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 · high confidenceA heap-based buffer overflow vulnerability in the network management service of Aruba AOS-8 and AOS-10 allows unauthenticated remote attackers to achieve remote code execution as a privileged user. Successful exploitation grants the attacker arbitrary code execution capabilities on the underlying operating system, potentially leading to complete system compromise, with possible denial-of-service conditions affecting the service process.

It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.
-
Identify the Aruba product and versionRun 'show version' on the device CLI or check the WebUI dashboard for the OS version informationAffected if The displayed version falls within any of the affected ranges: AOS 6.5.4.0 to 8.10.0.21, 8.11.0.0 to 8.12.0.6, 8.13.0.0 to 8.13.1.1, 10.4.0.0 to 10.4.1.10, or 10.5.0.0 to 10.7.2.2; or for SD-WAN, versions 8.6.0.4-2.2.0.0 through 8.6.0.4-2.2.0.7 or 8.7.0.0-2.3.0.0 through 8.7.0.0-2.3.0.9
-
Verify the network management service is enabledCheck the device configuration for enabled management interfaces such as the WebUI (HTTPS/HTTP), REST API, or other management daemon services using 'show running-config' or 'show web-server configuration'Affected if Any network management service (WebUI, API, management daemon) is enabled and listening on accessible network interfaces
-
Confirm management interface exposureReview interface bindings and access lists: check 'show ip interface', 'show management-interface', or firewall policies to determine if management services are bound to production or management networks rather than isolated VLANsAffected if The network management service is bound to interfaces accessible from untrusted networks or the management interface is exposed externally (e.g., WAN-facing or without VPN)
The environment is affected if the device runs a vulnerable AOS or SD-WAN version AND has the network management service enabled and accessible from the network where attackers can reach it.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped8.10.0.228.12.0.78.13.1.2
Apply vendor-released patches for AOS-8 and AOS-10 as soon as available. If patches are unavailable, consider network segmentation to restrict access to the management interface and implement additional monitoring for exploitation indicators.
ArubaOS: 8.10.0.22+ (8.10.x), 8.12.0.7+ (8.11.x), 8.13.1.2+ (8.13.x), 10.4.1.11+ (10.4.x); SD-WAN: version > 8.6.0.4-2.2.0.7 or > 8.7.0.0-2.3.0.9
- 1. Identify the currently installed ArubaOS or SD-WAN version by accessing the device CLI or web interface
- 2. Determine the appropriate upgrade path based on current version: for 8.10.x branch upgrade to >= 8.10.0.22; for 8.11.x branch upgrade to >= 8.12.0.7; for 8.13.x branch upgrade to >= 8.13.1.2; for 10.4.x branch upgrade to >= 10.4.1.11
- 3. Download the appropriate firmware from support.hpe.com (Aruba support portal)
- 4. Review release notes for the target version to ensure compatibility with your deployment
- 5. Create a backup of the current configuration
- 6. Upload the new firmware to the device using the CLI (upgrade-software) or WebUI
- 7. Reboot the device to apply the new firmware
- 8. Verify the device is running the patched version after reboot
