Kali Linux - Vulnerability Analysis Tools

Vulnerability analysis is a critical step in ethical hacking and penetration testing. Kali Linux provides a range of tools for analyzing vulnerabilities in systems, networks, and applications. In this article, we will explore the tools available in Kali Linux for vulnerability analysis, their features, and how to use them effectively.

Cisco Tools

Cisco Torch: This tool is used for mass scanning, fingerprinting, and exploiting vulnerabilities in Cisco routers.

Usage:

• Open the Terminal by clicking the left pane.
• Type the command: cisco-torch --parameter IP
• To view available parameters, type: cisco-torch ?

For example, if no vulnerabilities are found, the output will indicate that the target is secure. Cisco Torch is particularly useful in scanning large networks for potential weaknesses.

Cisco Auditing Tool (CAT): A PERL script designed to scan Cisco routers for vulnerabilities. It can also brute-force credentials on specific ports.

Usage:

• Open the terminal.
• Type the command: CAT -h hostname or IP
• To specify a port, add the parameter -p. For example: CAT -h 192.168.1.1 -p 23

Cisco Global Exploiter

The Cisco Global Exploiter (CGE) is an advanced tool for security testing. It supports various attack types, including denial-of-service and credential brute-force attacks. Exercise caution when using CGE in live environments, as some attacks can crash the targeted system.

Usage:

• Type the command: cge.pl IP vulnerability_number
• Refer to the list of vulnerabilities supported by CGE to choose the appropriate number.

BED

BED (Bruteforce Exploit Detector) is a tool for checking daemons for vulnerabilities like buffer overflows and format string vulnerabilities.

Usage:

• Test a service by specifying its protocol and target IP. For example: bed -s HTTP -t 192.168.1.102

BED is especially effective for detecting issues in custom or less commonly used daemons.

Hping3

Hping3 is a versatile network tool for packet crafting and analysis. It can send TCP, UDP, ICMP, and RAW-IP packets, perform traceroutes, and test firewall rules.

Usage:

• View help: hping3 -h
• Send crafted packets: hping3 domain_or_IP -parameter

Best Practices for Using Vulnerability Analysis Tools

When using these tools, always ensure you have proper authorization to test the target systems. Misusing these tools can lead to severe consequences, including legal action. Follow these best practices:

• Work in a controlled environment or sandbox.
• Document all actions and findings.
• Report vulnerabilities to the system owner responsibly.

These tools, when used ethically, can significantly enhance the security posture of systems and networks.
