Extreme switch won’t be affected as long as “https” is disabled like below test result but it is strongly recommended not to use the version which does not have the patch.  

Below is the result of the nmap to identify the vulnerability.

PJ, we just verified the patch is definitely posted.  If you are not able to access it, I suggest you call into the TAC so we can get this sorted out for you ASAP.

thanks

This reply was created from a merged topic originally titled
Extreme Networks Response to US-CERT Vulnerability Advisory VU#720951.


Article ID: 16131 

Products
Black Diamond Series X8, 8900, and 8800 running EXOS version 15.4.1
Summit Series X770, X670, X480, X460, X440, X430, E4G-200, and E4G-400 running EXOS version 15.4.1
64-bit (Ubuntu) hardware-based and virtual NetSight appliances running version 4.4, 5.0, 5.1, or 6.0
64-bit (Ubuntu) hardware-based and virtual NAC & IA appliances running version 5.0, 5.1, or 6.0
64-bit (Ubuntu) hardware-based and virtual Purview appliances running version 6.0

Discussion
On April 7 2014, US-CERT issued advisory 720951.
(This issue is also tracked as CVE-2014-0160, and discussed in 16130.)

The advisory overview...
OpenSSL 1.0.1 contains a vulnerability that could disclose sensitive private information to an attacker. This vulnerability is commonly referred to as "heartbleed."

The advisory impact...
By attacking a service that uses a vulnerable version of OpenSSL, a remote, unauthenticated attacker may be able to retrieve sensitive information, such as secret keys. By leveraging this information, an attacker may be able to decrypt, spoof, or perform man-in-the-middle attacks on network traffic that would otherwise be protected by OpenSSL.

The advisory lists a number of affected vendors, including Extreme Networks and Enterasys Networks.

If within the advisory the hyperlinked Extreme Networks or Enterasys Networks Information still reads "No statement is currently available from the vendor regarding this vulnerability.", then please refer to this statement (.pdf, 200 KB) submitted to US-CERT on April 11 2014.

EXOS 15.4.1.3-patch1-10 is available for download via eSupport's "Download Software Updates" link.
The NetSight patch is available for download from the NMS Product page, or here (1.5 MB).
A set of Dragon signatures was released on April 9, to assist in detecting attempted exploits.

Heartbleed OpenSSL Vulnerability in NMS/Oneview or Wireless Controller.


Are NMS/Oneview, or the wireless controller at risk of the Heartbleed OpenSSL vulnerability?  What revision levels are at risk?  Is there a corporate statement of exposure risk and mitigation?

This reply was created from a merged topic originally titled
Response to "Heartbleed" CVE-2014-0160 OpenSSL vulnerability.


Article ID: 16130 

Products
The issue affects products which use OpenSSL 1.0.1 (March 2012) through 1.0.1f for SSL/HTTPS support.
OpenSSL 1.0.1g, released April 7 2014, resolves the vulnerability.

Affected:
  • Black Diamond Series X8, 8900, and 8800 running EXOS version 15.4.1
  • Summit Series X770, X670, X480, X460, X440, X430, E4G-200, and E4G-400 running EXOS version 15.4.1
  • 64-bit (Ubuntu) hardware-based and virtual NetSight appliances running version 4.4, 5.0, 5.1, or 6.0
  • 64-bit (Ubuntu) hardware-based and virtual NAC & IA appliances running version 5.0, 5.1, or 6.0
  • 64-bit (Ubuntu) hardware-based and virtual Purview appliances running version 6.0
Discussion
Vulnerability notification CVE-2014-0160 was released on April 7 2014.
Its Overview states:
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.

The high visibility and potentially high impact of this issue has spawned many follow-up reports which are visible in a web search for "heartbleed" or "CVE-2014-0160".

Patches have been developed to address this vulnerability across all affected products, and these will be included in subsequent GA releases. Patch availability is discussed in 16131, which addresses this issue being tracked as US-CERT Vulnerability Advisory VU#720951.

Does anyone have any information on whether or not and which Enterasys or Extreme products are affected by this vulnerability?

Hi

After patch the NetSight, how can I make sure the bug has been fixed?

Thanks.

This information was added yesterday to the end of the NetSight Patch readme file, in the copy that is accessible from the end of the "Article ID: 16131" as both embedded and hyperlinked above:

Optional verification of results:
In 'dpkg -l | grep ssl' command output, the "libssl1.0.0" and "openssl" packages should display version "1.0.1-4ubuntu5.12" if the patch has been successfully applied.

The last time I checked (yesterday), it had not yet been added to the copy out on the NMS Product page.
