Understand the Heartbleed Vulnerability and Remediate

Analyst Coverage

“Cybercriminals are known to steal SSH keys or manipulate which keys are trusted to gain access to source code and other valuable intellectual property” Read More

“Advanced threat detection provides an important layer of protection but is not a substitute for securing keys and certificates that can provide an attacker trusted status that evades detection.” Read More

"Basically, the enterprise is a sitting duck."

"PKi is under attack...Advanced and persistent adversaries go for keys" Read More

"When there are many hundreds of certificates from a variety of certificate authorities, the only ecumenical [universal], nonproprietary provider of a certificate management solution is Venafi. Other CA management systems are biased toward the particular CA by, for example, only supporting renewals from that specific CA." Read More

"No CISO could consider having tens of thousands of unknown network ports open and have no way to control them. But that’s the alarming reality today with regards the trust established by keys and certificates..." Read More

"Organizations with roughly 200 or more documented X.509 certificates in use are high-risk candidates for unplanned expiry and having certificates that have been purchased but not deployed." Read More

"Technology critical to cloud computing is in clear and present danger...attacks on Secure Shell (SSH) keys present the most alarming threat arising from failure to control trust." Read More

Understanding the Heartbleed Vulnerability

What is the Heartbleed vulnerability?

The Heartbleed vulnerability is a coding error in the OpenSSL library. Without any privileged information or credentials, an attacker is able to copy keys and certificates from impacted web servers by abusing the TLS heartbeat extension.

 

What is the impact?

Over 66% of the world’s websites run Apache and NGINX with OpenSSL as the default. This figure does not include web servers behind firewalls. Any attacker can copy the keys and certificates from any of the impacted web servers without any trace.

OpenSSL is not only used on web servers. The Heartbleed vulnerability also affects email servers, chat servers, VPN’s, network appliance and client software.

What versions of OpenSSL does the Heartbleed vulnerability affect?

All software solutions utilizing the OpenSSL library version 1.0.1 through 1.0.1f are susceptible to the Heartbleed vulnerability.

How long has the Heartbleed vulnerability been in the wild?

The Heartbleed vulnerability has been in the wild since 2011 when it was introduced in version 1.0.1.
