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
File Upload vulnerability in Shibang Communications Co., Ltd. IP network intercom broadcasting system v.1.0 allows a local attacker to execute arbitrary code via the my_parser.php component.

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

A file upload vulnerability in the my_parser.php component of Shibang Communications IP network intercom broadcasting system v1.0 allows a local attacker to upload malicious files and execute arbitrary code. The component lacks proper validation of uploaded file types, contents, or storage locations, enabling remote code execution.

MitigationImplement strict file upload validation including allowlist-based MIME type checking, file content inspection, storing uploads outside the webroot with randomized filenames, and disabling script execution in the upload directory.

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 installed version of the IP network intercom broadcasting system
    Locate the system management interface or check product documentation for the version number. Compare against v1.0 which is the affected version.
    Affected if The system is running version 1.0 of Shibang Communications IP network intercom broadcasting system
  2. Locate the my_parser.php component
    Search the web server document root for the file my_parser.php. Common paths may include /admin/, /api/, or /php/ directories within the web application structure.
    Affected if The file my_parser.php exists in a web-accessible directory on the server
  3. Verify the file upload endpoint is exposed
    Attempt to access my_parser.php via HTTP/HTTPS request or examine web server access logs for requests to this endpoint.
    Affected if The my_parser.php component is accessible via the web server and accepts file upload requests
  4. Inspect upload directory configuration
    Check the web server configuration and my_parser.php source code to determine where uploaded files are stored. Verify if the storage location is within the webroot.
    Affected if Uploaded files are stored in a directory accessible via web (within webroot) rather than outside the document root
  5. Check if script execution restrictions are disabled in upload directories
    Examine web server configuration (e.g., .htaccess for Apache, nginx config) for the upload directory. Verify if execution permissions are allowed for uploaded files.
    Affected if Uploaded files can be executed as scripts (e.g., .php files run when accessed via web) due to missing execution restrictions

A user is affected if they are running version 1.0 of Shibang Communications IP network intercom broadcasting system with the my_parser.php component accessible and storing uploads in web-accessible directories without script execution restrictions.
