Denial of Service in Cisco Catalyst 2900XL Switch

CVE-2001-0566

Summary

The Cisco Catalyst 2900XL Switch is vulnerable to a denial of service attack where a remote attacker can crash the device by sending an empty UDP packet to port 161, which is used for SNMP communications. This issue occurs when SNMP is disabled, making the switch susceptible to this type of exploit. Organizations using the Catalyst 2900XL should implement network security measures to prevent unauthorized access and monitor for unusual traffic patterns to mitigate the risk of this vulnerability.
