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
The SD-WAN Orchestrator 3.3.2 prior to 3.3.2 P3, 3.4.x prior to 3.4.4, and 4.0.x prior to 4.0.1 allows for executing files through directory traversal. An authenticated SD-WAN Orchestrator user is able to traversal directories which may lead to code execution of files.

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 confidence

VMware SD-WAN Orchestrator contains a directory traversal vulnerability where authenticated users can manipulate file paths using traversal sequences (e.g., ../) to access files outside the intended directory and potentially execute arbitrary code. This stems from insufficient input validation on file path parameters in the web interface.

MitigationApply vendor-provided patches: upgrade to SD-WAN Orchestrator 3.3.2 P3, 3.4.4, 4.0.1 or later. Until patched, restrict network access to the management interface and minimize the number of privileged users.

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. Determine SD-WAN Orchestrator version
    Log into the SD-WAN Orchestrator web interface and navigate to the Administration or System settings section to locate the version information. Alternatively, check the login page footer or about page for the exact version number.
    Affected if The installed version matches one of the following: 3.3.2, or any version >= 3.4.0 but < 3.4.4, or any version >= 4.0.0 but < 4.0.1
  2. Verify management interface exposure
    Determine if the SD-WAN Orchestrator management interface is accessible from untrusted networks by reviewing firewall rules, VPN policies, or network segmentation configurations that control access to the Orchestrator IP or hostname on the management port (typically 443).
    Affected if The management interface is reachable from networks outside the trusted administrative zone, increasing exposure to authenticated attackers.
  3. Confirm user authentication is active
    Verify that the web-based management interface is configured with active user accounts. Check if local users, LDAP integration, or other authentication methods are enabled in the Orchestrator authentication settings.
    Affected if User authentication is enabled and active, which is required for an attacker to exploit this vulnerability as an authenticated user.
  4. Identify web interface endpoint accessibility
    Review web server logs or proxy configurations to determine if the Orchestrator web API endpoints that accept file path parameters are exposed. These typically include endpoints related to file uploads, downloads, or configuration imports.
    Affected if The web interface API endpoints accepting file path parameters are accessible to authenticated users.

A user is affected if the SD-WAN Orchestrator runs an affected version (3.3.2, 3.4.x before 3.4.4, or 4.0.x before 4.0.1), has its management interface network-accessible, and maintains active user authentication that could be leveraged by an attacker.
