Discovering interesting files and folders on web servers

During penetration tests, one of the everyday tasks that cannot be done manually is file and directory discovery hosted on web servers. There are several tools made for this task, but Nmap shines with its robust database that covers interesting files. In the database, you will find READMEs, database dumps, and forgotten configuration backups; common directories, such as administration panels or unprotected file uploaders; and even attack payloads to exploit directory traversals in vulnerable web applications. The http-enum NSE script also supports advanced pattern matching and can identify specific versions of web applications.

This recipe will look at how to use Nmap for web scanning to discover interesting files, directories, and even vulnerable web applications.
