Cisco IOS Software TCP Denial of Service Vulnerability - Cisco Systems

This script is (C) 2010-2014 Tenable Network Security, Inc.

Synopsis :

The remote device is missing a vendor-supplied security patch

Description :

Cisco IOS Software Release, 15.1(2)T is affected by a denial of
service (DoS) vulnerability during the TCP establishment phase. The
vulnerability could cause embryonic TCP connections to remain in a
SYNRCVD or SYNSENT state. Enough embryonic TCP connections in these
states could consume system resources and prevent an affected device
from accepting or initiating new TCP connections, including any
TCP-based remote management access to the device. No authentication is
required to exploit this vulnerability. An attacker does not need to
complete a three-way handshake to trigger this vulnerability;
therefore, this vulnerability can be exploited using spoofed packets.
This vulnerability may be triggered by normal network traffic. Cisco
has released Cisco IOS Software Release 15.1(2)T0a to address this
