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
Integer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x and other products, allows remote attackers to execute arbitrary code via a request with a crafted payload length.

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

Integer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x, allows remote attackers to execute arbitrary code via a request with a crafted payload length.

MitigationApply vendor patches for RealNetworks Helix Server/Helix Mobile Server to address the integer overflow; if patches unavailable, disable the AgentX service or implement network-level access controls to limit exposure.

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 installed Helix Server or Helix Mobile Server product
    Locate the Helix server installation directory and check for version identification files or executables. Common locations include /opt/HelixServer or C:\Program Files\RealNetworks\Helix Server. Look for version.info, about.html, or run 'server -v' if available.
    Affected if The product name matches Helix Server or Helix Mobile Server and the version falls within 11.0, 11.1, 12.0.0, 12.0.1, 13.0.0, or any version up to and including 13.1.1
  2. Verify the AgentX submodule is present
    Check for the presence of the AgentX++ library or module within the Helix Server installation. Look for files named agentx.dll, libagentx.so, or agentx.exe in the server's bin or lib directories.
    Affected if The AgentX component files exist in the installation directory
  3. Confirm AgentX service is enabled and running
    Check the server's configuration files (rmserver.cfg or similar) for AgentX settings. Look for 'AgentXEnabled' or 'agentx' entries. Also check if UDP port 705 (default AgentX port) is listening using netstat -an or ss -ulnp.
    Affected if AgentX is explicitly enabled in configuration or the AgentX port is found to be open and listening
  4. Inspect AgentX configuration for external exposure
    Review server access control settings in the configuration files. Determine if the AgentX service is bound to all interfaces (0.0.0.0) or restricted to localhost (127.0.0.1). Check for any firewall rules or ACLs protecting the AgentX port.
    Affected if AgentX is bound to 0.0.0.0 or an external IP address, making it network-accessible

The environment is affected if a Helix Server or Helix Mobile Server version between 11.0 and 13.1.1 inclusive is installed with the AgentX service enabled and network-accessible.
