Description:
Alexey Sintsov has reported a vulnerability in Motorola SB5100E, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to the improper handling of LAND packets (IP packets with the same destination and source IP and port, and with the SYN flag set). This can be exploited to cause a DoS by crashing the device. A physical restart is reportedly required to resume normal operation.
Solution:
Restrict use to within trusted networks only.
Provided and/or discovered by:
