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
Attackers can cause a denial of service in Ascend MAX and Pipeline routers with a malformed packet to the discard port, which is used by the Java Configurator tool.

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 denial-of-service vulnerability exists in Ascend MAX and Pipeline routers where sending a malformed packet to the discard port (used by the Java Configurator tool) causes the device to crash or become unresponsive.

MitigationSince these are legacy 1999-era routers likely past end-of-life, apply network access controls to block external traffic to the discard port, or replace with current hardware if the devices are still in production use.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Ascend router models on the network
    Inventory network devices and check for Lucent Ascend MAX, Pipeline, or Tnt routers by querying SNMP, checking device banners, or reviewing network topology documentation
    Affected if Any of these three router models (MAX, Pipeline, or Tnt) are present in the environment
  2. Confirm firmware version
    Access the router console or management interface and run the version command to display the installed firmware version
    Affected if The firmware version matches 1.0, 2.0, 3.0, 4.0, or 5.0 for MAX; 1.0-6.0 for Pipeline; or 1.0 or 2.0 for Tnt
  3. Check if discard port is listening
    Perform a port scan or use 'netstat' from an adjacent system to check if UDP port 9 (discard port) is open and listening on the router
    Affected if UDP port 9 is open and accessible on the device
  4. Verify Java Configurator is enabled
    Check the router configuration for Java Configurator service settings, typically accessible via the management interface or configuration files
    Affected if Java Configurator is enabled and the discard port is in use

A user is affected if they have a Lucent Ascend MAX, Pipeline, or Tnt router running the specified firmware versions with the discard port open and Java Configurator enabled.
