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
Heap-based buffer overflow in the NTLM authentication functionality in RealNetworks Helix Server and Helix Mobile Server 11.x, 12.x, and 13.x allows remote attackers to have an unspecified impact via invalid base64-encoded data.

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

Heap-based buffer overflow vulnerability in the NTLM authentication module of RealNetworks Helix Server and Helix Mobile Server (versions 11.x, 12.x, 13.x). The overflow occurs when processing invalid base64-encoded credentials during NTLM authentication handshake, allowing heap memory corruption that can be exploited for remote code execution.

MitigationUpgrade to the latest Helix Server version or apply vendor-provided patches; alternatively, disable NTLM authentication if not required and use stronger authentication mechanisms.

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 Helix Server installation
    Check for the presence of Helix Server or Helix Mobile Server by examining common installation directories (e.g., C:\Program Files\Real\Helix Server or /opt/HelixServer) and looking for executable files such as rmserver.exe or helixserver. On Linux, check for process names containing 'helix' using 'ps aux | grep -i helix'.
    Affected if The software is not installed or no Helix Server process is running.
  2. Determine installed Helix Server version
    Locate the version information in the server's about page, license file, or check the binary properties of rmserver.exe (right-click > Properties > Version) on Windows. On Linux, examine the version string in the server binary or check /var/opt/realplatform/helix/server/VERSION if it exists.
    Affected if The installed version matches any of these affected versions: 11.0, 11.1, 11.1.2, 11.1.3, 12.0, 12.0.0, 13.0, or 13.0.0.
  3. Confirm NTLM authentication is enabled
    Examine the Helix Server configuration file (usually rmserver.cfg or helix.cfg in the server's config directory) for authentication settings. Look for entries containing 'NTLM', 'AuthScheme', or 'Authentication' and verify whether NTLM authentication is explicitly enabled or listed as an allowed method.
    Affected if NTLM authentication is listed as an enabled or allowed authentication mechanism in the server configuration.
  4. Verify NTLM authentication endpoint exposure
    Check if the server is listening on ports that accept NTLM authentication (typically port 554 for RTSP or other media streaming ports). Use 'netstat -an | grep -E "554|7070|8080"' on Linux or check open ports on Windows to confirm the server is reachable and potentially exposing the vulnerable authentication module.
    Affected if The Helix Server is running and accepting connections on ports that support NTLM authentication.

You are affected if Helix Server or Helix Mobile Server versions 11.0 through 13.0.0 are installed with NTLM authentication enabled and accessible over the network.

Mitigation

Upgrade to the latest Helix Server version or apply vendor-provided patches; alternatively, disable NTLM authentication if not required and use stronger authentication mechanisms.
