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
An improper authentication vulnerability affecting Vonets industrial wifi bridge relays and wifi bridge repeaters, software versions 3.3.23.6.9 and prior enables an unauthenticated remote attacker to bypass authentication via a specially crafted direct request when another user has an active session.

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 authentication bypass vulnerability in Vonets industrial wifi bridge relays and repeaters running software version 3.3.23.6.9 or prior. An unauthenticated remote attacker can bypass authentication by sending a specially crafted direct request that exploits an active session from another legitimate user.

MitigationImmediately identify and inventory all affected Vonets devices in the network, contact the vendor for available firmware updates that address this vulnerability, and if no patch is available, consider network segmentation to limit exposure of these devices to untrusted networks.

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 management interface or check the device label to confirm the model. Affected models are: Var1200 H, Var1200 L, Var600 H, Vap11ac, Vap11g 500s, Vbg1200, Vap11s 5g, and Vap11s.
    Affected if The device is one of these Vonets models and is accessible on the network.
  2. Check the firmware version
    Log into the device web interface and navigate to the Status or System Information page to view the firmware version. Alternatively, check the admin interface or device documentation for version information.
    Affected if The firmware version is 3.3.23.6.9 or lower.
  3. Confirm web management interface is accessible
    Attempt to access the device HTTP interface from a network location. The vulnerability is exploited via direct HTTP requests to the web management interface.
    Affected if The device web interface is reachable over HTTP from your testing location.
  4. Verify active session handling
    Examine the device session management configuration if accessible. The vulnerability exploits how active sessions are handled during authentication. Check if multiple users can maintain sessions simultaneously.
    Affected if The device maintains persistent web sessions that can be reused or hijacked.

If the device is a Vonets model from the affected list, runs firmware version 3.3.23.6.9 or lower, and has its web management interface exposed, the environment is likely affected by this authentication bypass.
