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
Multiple OS command injection vulnerabilities affecting Vonets industrial wifi bridge relays and wifi bridge repeaters, software versions 3.3.23.6.9 and prior, enable an authenticated remote attacker to execute arbitrary OS commands via various endpoint parameters.

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

Multiple OS command injection vulnerabilities in Vonets industrial wifi bridge devices (versions 3.3.23.6.9 and prior) allow authenticated remote attackers to execute arbitrary OS commands through various endpoint parameters. The vulnerabilities stem from insufficient input validation when handling user-supplied data in web interface endpoints, enabling command injection via shell metacharacters.

MitigationUpgrade to a patched firmware version from Vonets; if unavailable, restrict network access to the device management interface and review for suspicious administrative accounts or unexpected processes.

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 Vonets device model
    Access the device web interface or check device labeling to confirm the exact model (Var1200 H/L, Var600 H, Vap11ac, Vap11g 500s, Vbg1200, Vap11s 5g, or Vap11s)
    Affected if The device is any of these models and is in scope for this CVE
  2. Check the installed firmware version
    Log into the device web interface and navigate to the status or system information page to view the firmware version. Compare against 3.3.23.6.9
    Affected if The firmware version is 3.3.23.6.9 or earlier (lower version numbers indicate the vulnerable release)
  3. Verify the web management interface is enabled
    Confirm the device has its HTTP/HTTPS web interface accessible. This is typically on port 80 or 443. Check device network settings or attempt to access the interface
    Affected if The web management interface is enabled and accessible - this is the attack vector for command injection
  4. Determine if remote management is exposed
    Check the device network configuration to see if the web interface is bound to WAN or external network interfaces, or use network scanning to detect the device management port from outside your LAN
    Affected if The web interface is exposed to untrusted networks (not just trusted LAN segments)

Your environment is affected if you have any Vonets device (Var1200, Var600, Vap11ac, Vap11g 500s, Vbg1200, Vap11s 5g, or Vap11s) running firmware version 3.3.23.6.9 or earlier with the web management interface enabled.

dbcve · scoped
Upgrade available Upgrade to a release after 3.3.23.6.9
Interim mitigation

Upgrade to a patched firmware version from Vonets; if unavailable, restrict network access to the device management interface and review for suspicious administrative accounts or unexpected processes.

Recommended fix Moderate confidence

Latest available Vonets firmware version beyond 3.3.23.6.9 (contact Vonets vendor for specific fixed release)

  1. 1. Identify the specific Vonets device model from the affected product list (Var1200 H, Var1200 L, Var600 H, Vap11ac, Vap11g 500s, Vbg1200, Vap11s 5g, or Vap11s)
  2. 2. Access the device management interface or Vonets support website
  3. 3. Check for available firmware updates beyond version 3.3.23.6.9
  4. 4. Download the latest firmware version available from the official Vonets vendor
  5. 5. Follow the vendor's documented firmware upgrade procedure to apply the update
  6. 6. After upgrading, verify the device is functioning correctly and the firmware version has been updated
