  • 1.  Heartbleed - CVE-2014-0160 Problem

    Posted Apr 08, 2014 04:50 AM

    We have tried to http://filippo.io/Heartbleed/ web page and found that we hit the valnurability.

     

    Please help. We could not find any info on ARUBA.

     

    Also, according to debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=743883) all private keys should be changed immediately!

     

     

    Sincerly,

    good question, im currently wondering the same and would appriciate a reaction from Aruba.

     

    of course best thing to do is open a support case, but still an announcement by Aruba would help to prevent everyone from doing that :)

     

    btw: rdemir could you add Heartbleed to your subject, makes it easier for other to see it.

    It seems ClearPass and ArubaOS are impacted:

    seems to be version dependent, got a 6.2.5 version which doesnt seem affected.

     

    airwave 7.6.3 neither.



  • 6.  RE: Heartbleed - CVE-2014-0160 Problem

    Posted Apr 08, 2014 11:14 AM

    That test is ClearPass 6.2.5. We have tested with ArubaOS 6.3.1.4 and it seems to be vulnerable.

     

    I'm wondering if FreeRADIUS within ClearPass is also vulnerable.

    How do you test ArubaOS version?

    what do you exactly mean? you can test it via the webinterface, that is the part that probably uses OpenSSL.

     

    if you webinterface isnt reachable via the internet you already excluded a big attack surface. within your own network you might be able to restrict access only from a management subnet.

     

    to test internal you can use the PoC python script or use this openssl command: openssl s_client -connect google.com:443 -tlsextdebug and look for the server extension heartbeat string in the begin.

    You will probably be vulnerable when:

     

    * You are using a captive portal which is running on the controller and/or ClearPass

    * You are using the controller for VIA

     



  • 10.  RE: Heartbleed - CVE-2014-0160 Problem

    Posted Apr 08, 2014 01:09 PM

     

    Aruba controllers are also impacted.

     

    One POC run against a 7220 controllers running 6.3.1.4 returned back what looks to be part of an XML configuration file and at least CA information for the pub/priv key combination that ships as the default cert on the controllers. 

     

    I went into our Airwave 7.7.10 system and ran "yum update" which installed a patched openssl via CentOS upstream and the POC fails against it.

    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.

    Posted Apr 08, 2014 04:49 PM

    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.



  • 13.  RE: Heartbleed - CVE-2014-0160 Problem

    Posted Apr 08, 2014 08:31 PM

    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.



  • 14.  RE: Heartbleed - CVE-2014-0160 Problem

    Posted Apr 09, 2014 03:56 AM

    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.



  • 15.  RE: Heartbleed - CVE-2014-0160 Problem

    Posted Apr 09, 2014 06:36 AM

    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.

    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".

    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.

    Where in the Aruba Support Center -> Download software I need to go to download the pach?

     

    The pach is a OS update?
