==2E[DESCRIPTION]=2E
NetPerformer Frame Relay Access Device (FRAD) is switching & routing device
that support Ethernet and SNA protocols, Voice, etc=2E This device mainly
used for connecting distributed WAN network through frame relay or ATM
network=2E



==2E[DETAILS]=2E
1=2E Telnet long username Buffer Overflow=2E
Passing an overly long username (>4550 char) against telnet service causes
device to reboot=2E Successful remote exploitation will possibly allows an
attacker gaining access into the device=2E

2=2E ICMP Land Attack
By sending specially crafted ICMP packets will causes the device to be hang
up and resetting current TCP handshake connection=2E In earlier version
possibly will make device to reboot=2E
