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 in the CLI of stand-alone Cisco IOS XE SD-WAN Software and Cisco SD-WAN Software could allow an authenticated, local attacker to delete arbitrary files from the file system of an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary file path information when using commands in the CLI of an affected device. A successful exploit could allow the attacker to delete arbitrary files from the file system of the affected device.

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

A vulnerability in the CLI of Cisco IOS XE SD-WAN and Cisco SD-WAN Software allows authenticated local attackers to delete arbitrary files due to insufficient input validation. Attackers can inject malicious file path information into CLI commands to bypass restrictions and remove any file on the affected device's filesystem.

MitigationApply the vendor-provided patch or upgrade to a fixed software version. Additionally, limit CLI access to trusted personnel only and monitor for unusual or malformed CLI command patterns.

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 the Cisco SD-WAN product
    Log into the device CLI and run 'show version' or 'show sdwan version' to determine which SD-WAN component is running (Vbond Orchestrator, Vmanage, Vsmart Controller, or IOS XE SD-WAN)
    Affected if The device is running any of the listed SD-WAN products (Vbond, Vmanage, Vsmart, or IOS XE SD-WAN)
  2. Check the installed software version
    Run 'show version' or 'show sdwan version' and locate the software version number. Compare it to the affected ranges: versions < 18.4.5 for Vbond/Vmanage/Vsmart, or versions < 16.10.1 for IOS XE SD-WAN
    Affected if The installed version is below 18.4.5 (for Vbond/Vmanage/Vsmart) or below 16.10.1 (for IOS XE SD-WAN)
  3. Verify CLI access exists
    Confirm the device has CLI interface available. This vulnerability requires authenticated local CLI access to exploit. Check if CLI accounts exist with 'show users' or similar command
    Affected if CLI access is available to any user account on the device
  4. Review system logs for file deletion events
    Check system logs (via 'show log' or logging buffer) for commands that include unusual file path patterns, particularly attempts to delete files outside normal operation directories
    Affected if Logs show CLI commands with suspicious path traversal patterns or unexpected file deletions

The environment is affected if the device runs a vulnerable Cisco SD-WAN product version (below 18.4.5 or below 16.10.1 depending on product) and has CLI access available to authenticated users.

Upgrade available Upgrade to 16.10.1 / 18.4.5 or later
Fixed in 16.10.118.4.5
Interim mitigation

Apply the vendor-provided patch or upgrade to a fixed software version. Additionally, limit CLI access to trusted personnel only and monitor for unusual or malformed CLI command patterns.

Recommended fix High confidence

18.4.5 for Vbond Orchestrator, Vmanage, Vsmart Controller, and SD-WAN; 16.10.1 for IOS XE SD-WAN

  1. Identify the current version of the affected SD-WAN component (Vbond Orchestrator, Vmanage, Vsmart Controller, or IOS XE SD-WAN) using the CLI or management interface
  2. Download the fixed software version from Cisco (18.4.5 for Vbond/Vmanage/Vsmart/SD-WAN, or 16.10.1 for IOS XE SD-WAN)
  3. Follow Cisco SD-WAN upgrade procedures to install the fixed software version
  4. Verify the upgrade was successful by checking the software version post-upgrade
  5. Ensure only authorized administrative users have CLI access to prevent local authenticated exploitation
Caveat Review Cisco SD-WAN release notes for any compatibility or configuration changes before upgrading
