Nikto v2.5 releases – WebAPP Penetration Testing Tool

Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6700 potentially dangerous files/programs, checks for outdated versions of over 1250 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software. Scan items and plugins are frequently updated and can be automatically updated.

Nikto is not designed as a stealthy tool. It will test a web server in the quickest time possible and is obvious in log files or to an IPS/IDS. However, there is support for LibWhisker’s anti-IDS methods in case you want to give it a try (or test your IDS system).

Not every check is a security problem. Some items are “info only” type checks that look for things that may not have a security flaw, but Pentester may not know are present on the server. These items are usually marked appropriately in the information printed. There are also some checks for unknown items that have been seen scanned for in log files.

The goal of the project is to examine a web server to find potential problems and security vulnerabilities, including:

• Server and software misconfigurations
• Default files and programs
• Insecure files and programs
• Outdated servers and programs
• Pointers to lead a human tester to better manual testing

The vulnerability scanner discovers various issues that are potential security problems for your web server. The types of issues Nikto can identify are:

• Fingerprint the web server type and version
• Report old versions of server software if it contains known vulnerabilities
• Discover web server configuration problems (directory listing, backup files, old configuration files, etc)
• Identify specific web applications that are running on the web server
• Check for known application vulnerabilities
