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
Cross-site request forgery (CSRF) vulnerability in MAHO-PBX NetDevancer Lite/Uni/Pro/Cloud prior to Ver.1.11.00, MAHO-PBX NetDevancer VSG Lite/Uni prior to Ver.1.11.00, and MAHO-PBX NetDevancer MobileGate Home/Office prior to Ver.1.11.00 allows a remote unauthenticated attacker to hijack the user authentication and conduct user's unintended operations by having a user to view a malicious page while logged in.

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

Cross-site request forgery (CSRF) vulnerability in MAHO-PBX NetDevancer products (Lite/Uni/Pro/Cloud, VSG Lite/Uni, MobileGate Home/Office) prior to version 1.11.00 allows remote unauthenticated attackers to hijack authenticated user sessions and perform unauthorized operations by tricking logged-in users into visiting malicious web pages.

MitigationUpgrade to version 1.11.00 or later. If immediate patching is not possible, implement anti-CSRF tokens on all state-changing operations and configure SameSite cookie attributes to mitigate session hijacking.

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 NetDevancer product model
    Access the device's web administration interface or check the device label/documentation to confirm the exact model (Lite, Uni, Pro, Cloud, VSG Lite, VSG Uni, MobileGate Home, or MobileGate Office)
    Affected if The model is one of the NetDevancer product lines (Lite/Uni/Pro/Cloud, VSG Lite/Uni, MobileGate Home/Office)
  2. Determine the installed firmware version
    Log into the web administration panel and navigate to the system status or firmware information page, or access the device via CLI and run the appropriate version command
    Affected if The firmware version displayed is earlier than 1.11.00 (for example, 1.10.x, 1.9.x, etc.)
  3. Confirm web interface accessibility
    Verify that the device's web management interface is reachable over HTTP/HTTPS from a browser
    Affected if The web interface is accessible and the device is reachable on the network
  4. Verify session handling configuration
    Inspect the HTTP response headers from the web login page and authenticated requests, looking for SameSite cookie attributes and presence of CSRF tokens in forms
    Affected if The SameSite attribute is missing or set to 'None' on session cookies, and state-changing forms do not contain anti-CSRF tokens

You are affected if your NetDevancer device runs firmware version earlier than 1.11.00 and its web interface is accessible over the network.

Generated from the published advisory. Verify against your own configuration.

Upgrade available Upgrade to 1.11.00 or later
Fixed in 1.11.00
Interim mitigation

Upgrade to version 1.11.00 or later. If immediate patching is not possible, implement anti-CSRF tokens on all state-changing operations and configure SameSite cookie attributes to mitigate session hijacking.

Recommended fix High confidence
