Description:
A vulnerability has been reported in 3Com IntelliJack Switch NJ220, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when NJ220 processes loopback packets with a length field of zero. This can be exploited to cause NJ220 to restart and stop sending event packets to the Central Configuration Manager utility via a specially crafted loopback packet.
The vulnerability is reported in versions prior to 2.0.23.
