Step #6: Download and Install Some Additional Python Tools.Step #3: Update and Upgrade Your System.Step #2: Remove Any Existing Installation of Zenmap (Optional).Zenmap Download & Installation Steps in Linux.Hence, we see that it using the nmap scripts we can detect the vulnerabilities present on the system which can be a benefit for the Pen Testers.Īuthor: Jeenali Kothari is a Digital Forensics enthusiast and enjoys technical content writing. Here we see that all the scripts are loaded which can be used for vulnerability detection based on a particular service version. Let us load the scripts and check the service versions available on the target machine using nmap vulners. Then update the scripts in the NSE database. This script completely depends on having information on software versions therefore works with -sV flag. Nmap – Vulners is a NSE script using some well-known service to provide info on vulnerabilities. To exploit this vulnerability using MITM (Man in the Middle Attack), the attacker will then wait for a new TLS connection which will be followed by Client-Sever ‘Hello’ handshake messages. This script when run checks if a server is vulnerable to the SSL/TLS “CCS Injection” vulnerability. This script will open 2 separate connections to the server and then request for URL in base configuration. It checks for the vulnerability in the web server Slowloris DoS attack where it does not launch an actual DoS attack. The rmiregistry has default configuration which allows the class to load from remote URLs which may lead to remote code execution. This script checks whether Java rmiregistry allows class loads or not. On running this script, you see that the system is vulnerable. The SSL Poodle is a Man-in the middle exploit whose purpose is to take advantage of the security software running on SSL. This script checks for the presence of vsFTPd 2.3.4 backdoor vulnerability by attempting to exploit the backdoor using a harmful command. You see that on executing this script, you see that the system is susceptible to a vulnerability that is at high risk in nature. This vulnerability had been vastly exploited by ransomware like WannaCry. This script detects whether an SMBv1 server in Microsoft systems is vulnerable to the remote code execution which is commonly known as the EternalBlue vulnerability. One by one we will run these scripts and check for vulnerabilities. Here we see that a list of scripts are available to detect the vulnerabilities. So, let’s get started with listing all the scripts that are available for discovering the vulnerability. According to the needs of the users, they can pick from the range of available scripts or can create their scripts as per the requirements. competence, it allows executing these scripts side-by-side. Nmap Scripting Engine (NSE) has been one of the most efficient features of Nmap which lets users prepare and share their scripts to automate the numerous tasks that are involved in networking.
