Vulnerabilities in OpenSSL Running Version Prior to 1.0.1i is a high risk vulnerability that is one of the most frequently found on networks around the world. This issue has been around since at least 1990 but has proven either difficult to detect, difficult to resolve or prone to being overlooked entirely.
| Vulnerability Name: | Vulnerabilities in OpenSSL Running Version Prior to 1.0.1i |
|---|---|
| Test ID: | 16704 |
| Risk: | High |
| Category: | Encryption and Authentication |
| Type: | Attack |
| Summary: | Multiple vulnerabilities have been found in OpenSSL:
|
| Impact: | OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. (CVE-2014-0160) |
| Solution: | Upgrade to OpenSSL version 1.0.1i or newer: https://www.openssl.org/source/ |
| CVE: | CVE-2014-0160 CVE-2014-3506 CVE-2014-3507 CVE-2014-3508 CVE-2014-3509 CVE-2014-3510 CVE-2014-3511 CVE-2014-3512 CVE-2014-5139 |

Scanning For and Finding OpenSSL Running Version Prior to 1.0.1i
Use of Vulnerability Management tools are standard practice for the discovery of this vulnerability. The primary failure of VA in finding this vulnerability is related to setting the proper scope and frequency of network scans. It is vital that the broadest range of hosts (active IPs) possible are scanned and that scanning is done frequently. We recommend weekly. Your existing scanning solution or set of test tools should make this not just possible, but easy and affordable.
Penetration Testing (pentest) for this Vulnerability
The OpenSSL Running Version Prior to 1.0.1i is prone to false positive reports by most vulnerability assessment solutions. AVDS is alone in using behavior based testing that eliminates this issue. For all other VA tools security consultants will recommend confirmation by direct observation. In any case penetration testing tools for discovery of OpenSSL Running Version Prior to 1.0.1i produces the highest discovery accuracy rate, but the infrequency of this expensive form of testing degrades its value. The ideal would be to have pentesting accuracy and the frequency and scope possibilities of VA solutions.
Security Updates onOpenSSL Running Version Prior to 1.0.1i
Given that this is one of the most frequently found vulnerabilities, there is ample information regarding mitigation online and very good reason to get it fixed. Hackers are also aware that this is a frequently found vulnerability and so its discovery and repair is that much more important. It is so well known and common that any network that has it present and unmitigated indicates "low hanging fruit" to attackers.
