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.

Lucent Ascend MAX Router 5.0 and earlier, Lucent Ascend Pipeline Router 6.0.2 and earlier and Lucent DSLTerminator allows remote attackers to obtain sensitive information such as hostname, MAC, and IP address of the Ethernet interface via a discard (UDP port 9) packet, which causes the device to leak the information in the response.
