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

Visualware MyConnection Server contains an exposed dangerous method (doRTAAccessUPass) that allows unauthenticated remote attackers to disclose sensitive information. The vulnerability stems from the method being accessible without proper authentication controls, enabling information disclosure in the context of the application.

MitigationImplement authentication and authorization checks for the doRTAAccessUPass method, or disable the method entirely if not required for legitimate functionality. Restrict network exposure to trusted users only.

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 Visualware MyConnection Server installation
    Locate and determine the installed version of Visualware MyConnection Server in your environment. Check application files, installed programs list, or service information for version details.
    Affected if The installed version is 11.3c
  2. Verify the application web interface is accessible
    Confirm that the MyConnection Server web interface is running and reachable. This is typically accessed via HTTP/HTTPS on the configured port.
    Affected if The web interface is accessible and responds to requests
  3. Test unauthenticated access to doRTAAccessUPass method
    Attempt to access the doRTAAccessUPass endpoint directly without providing credentials. This may appear as a URL path such as /doRTAAccessUPass or similar endpoint pattern.
    Affected if The endpoint responds without requiring authentication
  4. Check network exposure of the service
    Determine whether the MyConnection Server is exposed to untrusted networks or the public internet, or if it is restricted to trusted internal networks only.
    Affected if The service is accessible from untrusted network segments

You are affected if you are running Visualware MyConnection Server version 11.3c and the doRTAAccessUPass method is accessible without authentication.
