| Description | ||||
| PPTP and L2F are obsolete methods for implementing virtual private networks. Both protocols may be easy to use and readily available, but they have many well-known security issues and exploits. Encryption and authentication are both weak. | ||||

Details
Check Text (C-266998r1040760_chk)
Verify the AOS configuration with the following commands:
show ip access-list vpnlogon
show firewall-cp
If PPTP or TCP 1723 are permitted, this is a finding.
Fix Text (F-70825r1040759_fix)
Configure AOS with the following commands:
configure terminal
cd /mm
ip access-list session vpnlogon
any any svc-pptp deny
exit
write memory
cd /mynode
firewall cp
ipv4 deny any proto 6 ports 1723 1723
ipv6 deny any proto 6 ports 1723 1723
exit
write memory
