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
Reflected cross-site scripting vulnerability in MAHO-PBX NetDevancer series 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 inject an arbitrary script.

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

This is a reflected cross-site scripting (XSS) vulnerability in the web interface of MAHO-PBX NetDevancer series devices (Lite, Uni, Pro, Cloud, VSG, and MobileGate Home/Office versions prior to 1.11.00). A remote unauthenticated attacker can inject arbitrary JavaScript code through unsanitized user input that gets reflected back in HTTP responses, potentially allowing session hijacking or credential theft.

MitigationUpgrade to version 1.11.00 or later which contains the security patch. If immediate patching is not possible, implement web application firewall (WAF) rules to filter malicious script payloads in HTTP requests.

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 device model
    Access the device's web interface or check the device documentation/label to confirm it is a Maho Pbx NetDevancer product (Lite, Uni, Pro, Cloud, VSG, or MobileGate Home/Office)
    Affected if The device is a NetDevancer series product
  2. Check the firmware version
    Log into the web interface and navigate to the system status or firmware information page, or use the command line interface (CLI) to run 'show version' or similar command to retrieve the installed firmware version
    Affected if The firmware version is below 1.11.00
  3. Confirm web interface is accessible
    Attempt to reach the device's HTTP/HTTPS web interface from a client machine by entering the device IP address in a web browser
    Affected if The web interface is exposed and reachable over the network
  4. Identify reflected parameters in HTTP responses
    Use a web proxy or browser developer tools to capture HTTP requests and responses. Submit various user-supplied inputs (such as in login forms, search fields, or URL parameters) and observe if the same values are reflected verbatim in the response without proper encoding or sanitization
    Affected if User input is reflected in HTTP responses without encoding, indicating potential XSS vulnerability

The environment is affected if it is a Maho Pbx NetDevancer device (Lite, Uni, Pro, Cloud, VSG, or MobileGate Home/Office) running firmware version below 1.11.00 with the web interface accessible and unsanitized user input reflected in responses.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 1.11.00 or later
Fixed in 1.11.00
Interim mitigation

Upgrade to version 1.11.00 or later which contains the security patch. If immediate patching is not possible, implement web application firewall (WAF) rules to filter malicious script payloads in HTTP requests.

Recommended fix High confidence

Maho Pbx Netdevancer series (Firmware, VSG, MobileGate) version 1.11.00

  1. Obtain the firmware version 1.11.00 from the official vendor (Maho Pbx/ATE Mahoroba)
  2. Review vendor release notes for any specific upgrade instructions
  3. Backup current configuration before proceeding with upgrade
  4. Upload and install firmware version 1.11.00 following vendor-provided procedures
  5. Verify successful installation and confirm the system is operational
  6. Validate that the XSS vulnerability is resolved
Caveat Review vendor documentation for any configuration changes required between your current version and 1.11.00
