Re: [c-nsp] Cisco Security Advisory: Cisco ASA Software IKEv1 and IKEv2 Buffer Overflow Vulnerability

[Adrian M]

Be careful, It appears that something is broken with ARP on this release.
We have no ARP on lan interface, and somebody else has a similar problem:

[Jörg Kost]

Hi,

you could use snmptt with an Exec-Command (SendMail, SMS, …) or define 
it as a passive service alert in Nagios / Icinga / $YourMonitoring.

I looked at PagerDuty, but they don't do any SNMP trap parsing, and 
nothing

with set/clear.

datadog will do this without issue, and if you have a small number of hosts
it's nearly free.

Check_MK over OMD. Good event parsing capabilities. Easy to set up, nagios
core but rewritten app for much better performance. Multisite master/slave
capabilities +++.

Free or supported. Your pick.

I've used Zabbix, Nagios, etc to handle receiving and parsing traps,
set/clear etc.  Then have them send a trap (or via email to script that
sends a trap) to SIPShout to actually generate the callout.  It's worked
well.

Re: [c-nsp] Cisco Security Advisory: Cisco ASA Software IKEv1 and IKEv2 Buffer Overflow Vulnerability

Thus spake Andrew (Andy) Ashley (andre...@aware.co.th) on Thu, Feb 11, 2016 at 
02:35:51PM +:

It's worth noting that is not listed as a workaround (they typically use
branding like "infrastructure acl's" or some such) to mitigate it on the
affected box.  Upstream, yes that would seem to be intuitive.

Perhaps because you are corrupting the heap with fragments you are
outside of where the ACL is applied?

Re: [c-nsp] Cisco Security Advisory: Cisco ASA Software IKEv1 and IKEv2 Buffer Overflow Vulnerability

[Andrew (Andy) Ashley]

Is a control-plane ACL to limit isakmp traffic (UDP/500) to an affected ASA 
from desired sources enough to mitigate this attack, until upgrades can be 
performed?

Regards,

Andrew Ashley
