Automated Web app finger printing tool

In penetration testing finger printing the target web presence and enumerating as much as information possible is the primary step for an attacker/ security professional to discover vulnerability. With fingerprinting information attacker can develop an accurate attack scenario to exploit vulnerability in the software type/version being used by the target host. As important security vulnerabilities like SQL injection, buffer over flow are extremely depend on specific software version and software vendor, accurately identifying this sort of information becomes critical. Namp is one of the best tool serves the purpose for free.
Another tool currently released by Richard.sammet on, Basically this is a ruby based web application finger pritning tool using SQlite DB.
How it works
WAFP fetches the files given by the Finger Prints from a webserver and checks if the checksums of those files are matching to the given checksums from the Finger Prints. This way it is able to detect the detailed version and even the build number of a web application.
A Web Application Finger Print consits of a set of relative file locations in conjunction with their md5sums. It is made based on a production or example installation of a Web Application or just out of an extracted Web Application install files tarball. For this task, is to be used.
