Jumping in -

Updates are WIP Lelio. My expectation, as of timestamp of this email, is that 
UCM 9.x may not be affected. 10.x may be affected.

We are still validating.

Brian,

In reading the advisory, it's not clear if Communication Manager v9 and earlier 
is addressed. There is something called Cisco Unified Communication Server 
(UCM) 9.2 and earlier, but that's confusing because it's not the name and there 
is no v9.2 available.

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140409-heartbleed

Any chance on getting this cleared up?

Lelio

Should all be the same underlying OS.  10.x would be the only one I'd worry 
about until someone can check if it is vulnerable since it may have a newer 
openssl version.

Thanks Brian.

Can we assume that ELM and UCCx is also not affected? Same 9.x train.

Here we can see CUCM does not respond to the Heartbeat Request with any data:
<image.png>[X]

For the root inclined, we can find what openssl version is running:
[root@CUCM912 ~]# openssl version
OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

This new heartbeat bug isn't valid as OpenSSL didn't even implement responding 
to the Heartbeat Requests until version 1.0.1.  This is why CUCM doesn't 
respond with any data.

I don't have a 10.x box to check with right now.

Here's what I found testing against 9.1.2.10000.28 with a slightly modified 
python script:
bmeade@ubuntu:~$ python vulnscript 10.3.11.250
Connecting...
Sending Client Hello...
Waiting for Server Hello...
 ... received message: type = 22, ver = 0301, length = 1012
Sending heartbeat request...
Unexpected EOF receiving record header - server closed connection
No heartbeat response received, server likely not vulnerable

This is assuming the released script is checking for the vulnerability properly.

weird. for some reason i fixated on the date beneath the entry in the search 
listing which had 2011, which made more sense.

do you know if there is a more recent advisory?

I don't think that's the correct advisory.  That's a DoS vulnerability from 
2004.

Does anyone know if/when Cisco will be coming out with a security advisory 
about Open SSL and heartbleed?
