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 · unedited
A vulnerability exists that allows an authenticated attacker to overwrite an arbitrary file with attacker-controlled content via the web interface. Successful exploitation of this vulnerability could lead to full compromise the underlying host operating system.

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 confidence

This is an authenticated arbitrary file write vulnerability in a web interface that allows an attacker with valid credentials to overwrite any file on the system with content they control. This can be exploited to modify configuration files, deploy malicious scripts, or overwrite system files to achieve full operating system compromise.

MitigationImplement strict input validation and sanitization on all file write operations, enforce proper path traversal checks, and restrict file write capabilities to authorized directories only. Consider implementing allowlist-based file access controls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify product type and version
    Access the web interface or CLI and retrieve the system version information. For SD-WAN, look in the main dashboard or system settings. For ArubaOS, use 'show version' command in CLI or check the web UI footer/About page.
    Affected if The installed version falls within any of these ranges: SD-WAN >= 8.7.0.0-2.3.0.0 and < 8.7.0.0-2.3.0.7; ArubaOS 6.5.4.0 to < 6.5.4.23; 8.4.0.0 to < 8.6.0.18; 8.7.0.0 to < 8.7.1.10; 8.8.0.0 to <= 8.9.0.3; or exactly 10.3.0.0
  2. Confirm web interface is enabled
    Check if the web-based management interface (GUI) is accessible and enabled on the device. In ArubaOS, use 'show web-server' or check the HTTP/HTTPS service status. In SD-WAN, check the web portal configuration.
    Affected if The web interface is accessible from the network and accepts authentication requests. The vulnerability requires the web interface to be enabled.
  3. Verify authentication is configured
    Confirm that valid user accounts exist and can authenticate to the web interface. Check user accounts via CLI command 'show user-database' or through the web interface user management page.
    Affected if User accounts are created and authentication to the web interface is possible. This is an authenticated vulnerability, so valid credentials are required for exploitation.
  4. Check file upload/write functionality
    If you have access, examine the web interface for file upload, configuration import, or backup/restore features that handle file writes. These are the potential attack vectors for this vulnerability.
    Affected if The web interface exposes any feature that accepts file content and writes it to the filesystem, particularly configuration import, backup restore, or certificate upload features.

You are affected if you run ArubaOS or SD-WAN within the version ranges listed AND the web interface is enabled and accessible with valid user accounts.

Fixed in 6.5.4.238.6.0.188.7.0.0-2.3.0.7
Interim mitigation

Implement strict input validation and sanitization on all file write operations, enforce proper path traversal checks, and restrict file write capabilities to authorized directories only. Consider implementing allowlist-based file access controls.

Recommended fix High confidence

ArubaOS: 6.5.4.23+, 8.6.0.18+, 8.7.1.10+, or 8.9.0.4+ (depending on current branch); SD-WAN: 8.7.0.0-2.3.0.7+

  1. Identify the exact ArubaOS or SD-WAN version currently running on the affected device
  2. For ArubaOS devices: Upgrade to version 6.5.4.23 or later for the 6.5.4.x branch
  3. For ArubaOS devices: Upgrade to version 8.6.0.18 or later for the 8.4.x-8.6.x branch
  4. For ArubaOS devices: Upgrade to version 8.7.1.10 or later for the 8.7.x branch
  5. For ArubaOS devices: Upgrade to version 8.9.0.4 or later for the 8.8.x-8.9.x branch
  6. For SD-WAN devices: Upgrade to version 8.7.0.0-2.3.0.7 or later
  7. Verify the upgrade was successful and the vulnerability is remediated
  8. Ensure strong authentication is in place even after patching as this vulnerability requires authenticated access
