The remote device is missing a vendor-supplied security patch
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
