CVE-2018-0137

CWE-399


Summary

A vulnerability in the TCP throttling process of Cisco Prime Network could allow
an unauthenticated, remote attacker to cause a denial of service (DoS) condition
on an affected device.

The vulnerability is due to insufficient rate limiting protection for TCP
listening ports. An attacker could exploit this vulnerability by sending the
affected device a high rate of TCP SYN packets to the local IP address of the
targeted application. A successful exploit could allow the attacker to cause the
device to consume a high amount of memory and become slow, or to stop accepting
new TCP connections to the application.

There are no workarounds that address this vulnerability.
