DOS: Ascend Router (2)
This signature detects attempts to exploit a known vulnerability against Lucent routers. MAX Router 5.0, Pipeline Router 6.0, TNT Router 2.0, and all earlier versions are vulnerable. Attackers can send malformed packets to UDP/9 (Discard) to cause a denial of service (DoS) or crash the software.
Extended Description
Certain versions of Ascends (Lucent) router software listen on port 9 (UDP Discard). Ascend provides configuration tools for MAX and Pipeline routers that locate locally installed routers by broadcasting a specially formatted packet to UDP port 9. An attacker can send a similar but malformed packet to the same port that will cause MAX and Pipeline routers running certain software versions to crash.
