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 SEH-based buffer overflow in the BPQ32 HTTP Server in BPQ32 6.0.24.1 allows remote attackers with access to the Web Terminal to achieve remote code execution via an HTTP POST /TermInput request.

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 Structured Exception Handler (SEH) based buffer overflow vulnerability exists in the BPQ32 HTTP Server version 6.0.24.1. Attackers who have access to the Web Terminal interface can trigger the vulnerability by sending a specially crafted HTTP POST request to /TermInput, potentially executing arbitrary code on the target system.

MitigationRestrict network access to the BPQ32 Web Terminal service to trusted users only, and apply any vendor patches or updates when available. If no patch exists, consider disabling the HTTP server or implementing additional input validation/length checking on the /TermInput endpoint.

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 BPQ32 HTTP Server installation and version
    Locate the BPQ32 installation directory and check the version information, typically found in the executable properties or in a version file within the program folder. Common paths include C:\Program Files\BPQ32 or similar. Run 'dir' or use file properties to view version details.
    Affected if The installed version is 6.0.24.1 or falls within the affected version range
  2. Verify Web Terminal feature status
    Access the BPQ32 configuration interface or check configuration files for the Web Terminal feature. This is typically configured in the BPQ32.ini or through the web-based admin panel. Look for settings related to 'Web Terminal' or '/TermInput' endpoint enablement.
    Affected if Web Terminal feature is enabled and accessible to the attacker
  3. Confirm HTTP server is running and accessible
    Check if the BPQ32 HTTP server process is running (via Task Manager or command line tools like 'netstat -an | findstr 80' or 'tasklist'). Verify network accessibility by attempting to reach the HTTP server port from a browser or curl command.
    Affected if HTTP server is running and exposed on a network interface accessible to potential attackers
  4. Inspect for presence of vulnerable /TermInput endpoint
    Send a test HTTP request to the /TermInput endpoint using a tool like curl (e.g., curl -X POST http://target:port/TermInput) to confirm the endpoint exists and is processing requests.
    Affected if The /TermInput endpoint responds and processes POST requests, indicating the vulnerable code path is present

You are affected if BPQ32 HTTP Server version 6.0.24.1 is installed and the Web Terminal feature is enabled, allowing access to the vulnerable /TermInput endpoint.

Mitigation

Restrict network access to the BPQ32 Web Terminal service to trusted users only, and apply any vendor patches or updates when available. If no patch exists, consider disabling the HTTP server or implementing additional input validation/length checking on the /TermInput endpoint.
