Re: Heartbleed - CVE-2014-0160 Problem

Everyone -

 

I'm the security product manager at Aruba.  Please note that this is not a formal communication, we will be posting a formal communication on our website according to our security policy shortly.  That update will be posted here - http://www.arubanetworks.com/support-services/security-bulletins/

 

We are still assessing our exposure to this vulnerability, but it clearly impacts AOS 6.3.x and AOS 6.4.x.  We are working on updates to these as I type this, with the intention of publishing them as soon as we can finish and complete testing.

 

Until then, reducing access to the web GUI via control plane ACLs makes sense.  Other steps to limit exposure will be published as they are identified, and included in the security bulletin.

 

We are doing a careful analysis of the impact - the problem with this attack is that it gives the attacker access to some parts of the memory of the attacked system.  The advice on the internet to change all private keys is based on the fear that the key could be in this segment of memory.  We're validating whether or not this is the case, but you will have to decide your organization's tolerance to this particular risk.

 

Thanks for your understanding, and we'll keep you informed.

Re: Heartbleed - CVE-2014-0160 Problem

We have also done a POC where we were able to get the session-id from a logged-in Web-GUI user and then use that session-id to get access to the management console of the controller.

 

This is quite serious, limiting exposure of the controller's webserver is key here.

Re: Heartbleed - CVE-2014-0160 Problem

Which version had this behaviour?  This is completely different than the curren SSL vunlerability and it is something we've done several patches to fix.

Re: Heartbleed - CVE-2014-0160 Problem

Thanks for the info. I would like to remind the need for the "Management ACL" infrastructure for easy management. If we had such a function in ArubaOS;

 

management-ip 10.0.0.1

 

will suffice to protect the controller.

 

Thanks again.

Re: Heartbleed - CVE-2014-0160 Problem

This is at ArubaOS 6.3.1.4. Drop me an e-mail at arjan [at] securelink DOT nl if you want the output from ssltest.py.

 

@ hdemir: you can use the control plane firewall for this. This is "firewall cp" in the CLI.

Re: Heartbleed - CVE-2014-0160 Problem

i got this from aruba:

 

-----BEGIN PGP SIGNED MESSAGE-----

Hash: SHA1

 

Dear Aruba Networks Customer/Partner:

 

The purpose of this advisory is to address an important issue that affects Aruba Products that use the OpenSSL 1.0.1 Library.

 

Advisory Number 040814

CVE-2014-0160

 

 

TITLE

 

OpenSSL 1.0.1 library (Heartbleed) vulnerability.

 

 

SUMMARY

 

There is a very serious vulnerability that has been discovered in the OpenSSL 1.0.1 library. This vulnerability can allow an external attacker to extract segments of memory from a remote system without leaving any traces. This memory could contain vital security information, including private keys. These keys, in turn, could be used to mount a man-in-the-middle attack.

 

 

AFFECTED VERSIONS

 

— ArubaOS 6.3.x, 6.4.x

— ClearPass 6.1.x, 6.2.x, 6.3.x

 

Previous versions of these products used an earlier version of OpenSSL

that is not vulnerable. No other Aruba products, including AirWave, Instant,

run these compromised versions of OpenSSL. Aruba Central, Aruba Network’s

cloud-based Wi-Fi offering, upgraded their web infrastructure to the latest,

safe, version of OpenSSL on April 7 after the attack was first published.

 

 

DETAILS

 

OpenSSL is a very widely used library, and this vulnerability is likely to

affect many systems and websites. Aruba Networks uses this library in

different products to secure communications between our infrastructure and

various clients. This bug is in OpenSSL's implementation of the TLS/DTLS

(transport layer security protocols) heartbeat extension (RFC6520).

When exploited it leads to the leak from the server to the client. 

In some cases it has been demonstrated that key material may be part of

this memory leak.

 

 

DISCOVERY

 

This vulnerability was announced through CVE-2014-0160.

 

 

IMPACT

 

OpenSSL is used in a variety of ways in Aruba products, including:

* HTTPS communications via the Administrative Web GUI

* HTTPS communications via Captive Portals

* Secure RADIUS communication

* Secure communication with some third party APIs

 

CVSS v2 Base Score:5.0 (MEDIUM) (AV:N/AC:L/Au:N/C:P/I:N/A:N)

 

 

MITIGATION

 

As always, Aruba Networks recommends that best security practices are

followed, including reduction of possible attack surface areas by use

of access control methods such as network-level ACLs to restrict access.

However, given the ubiquitous use of OpenSSL, this may not completely

protect your infrastructure.

 

 

SOLUTION

 

Aruba Networks will be publishing patch releases for the effected products

by EOB April 10, 2014. We recommend that all customers upgrade to these

versions immediately.

 

ArubaOS 6.3.1.5

ArubaOS 6.4.0.3

ClearPass 6.1.X

ClearPass 6.2.X

ClearPass 6.3.X

 

Given that there is a chance that key material may already

have been compromised, we are further advising customers to consider

replacing your certificates after the upgrade is completed.

Re: Heartbleed - CVE-2014-0160 Problem

Thanks for the tip. We ask this for a long time from aruba and nobody tell about this feature. We will futher investigate how to use this "firewall cp".
