The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).
Base Score: 2.6 (AV:N/AC:H/Au:N/C:N/I:N/A:P)
Temporal Score: 2.1 (E:F/RL:O/RC:C)1. Prerequisite:
The attacker gains access to the device network and the SEP protocol is used;
2. Attacking procedure:
The device cannot free the buffer containing the malicious fields of the packet. As a result, attackers can craft and send a large number of such packets to the target device to exhaust the memory of the device and may cause the device to restart.
