Detect Heartbleed SSL Vulnerability with Nmap in Kali linux

This tutorial assumes you are working in a Kali Linux environment.

In this tutorial we will be scanning a target for the well known Heartbleed SSL Bug using the popular Nmap tool on Kali Linux. The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library and was introduced on 31 December on 2011 and released in March 2012. This weakness allows the attacker to steal information protected by the SSL/TLS encryption which is very commonly used to secure internet connections. The official name for Heartbleed is CVE-2014-0160. A fix has been released and deployed by many OS and application vendors but when a vulnerable version of OpenSSL is used or when applications haven’t been patched by the user or vendor, the vulnerability can still be exploited. With Nmap’s SSL-Heartbleed script it takes us just a couple seconds to check for this vulnerability and should be part of any penetration test.

nmap -sV -p 443 –script=ssl-heartbleed 192.168.1.0/24
