-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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 These vulnerabilities were 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. +---------------------------------------------------- OBTAINING FIXED FIRMWARE Aruba customers can obtain the firmware on the support website: http://support.arubanetworks.com Aruba Support contacts are as follows: 1-800-WiFiLAN (1-800-943-4526) (toll free from within North America) +1-408-754-1200 (toll call from anywhere in the world) The full contact list is at: http://www.arubanetworks.com/support-services/support-program/contact-support/ e-mail: support(at)arubanetworks.com Please, do not contact either "wsirt(at)arubanetworks.com" or "security(at)arubanetworks.com" for software upgrades.
