Buffer overflow vulnerabilities occur when an application copies user-controllable data into a memory buffer that is not sufficiently large to accommodate it. The destination buffer is overflowed, resulting in adjacent memory being overwritten with the user’s data. Depending on the nature of the vulnerability, an attacker may be able to exploit it to execute arbitrary … Read more
The barriers to automation described previously lead to a number of specific technical challenges that must be addressed in the creation of an effective vulnerability scanner. These challenges impinge not only upon the scanner’s ability to detect specific types of vulnerability, as already described, but also upon its ability to perform the core tasks of … Read more
A number of different tools exist for performing automated vulnerability scans of web applications. These scanners have the benefit of being able to test a large amount of functionality in a relatively short time, and in a typical application are often able to identify a variety of important vulnerabilities. Web application vulnerability scanners automate several … Read more

The manual request component of the integrated test suites provides the basic facility to issue a single request and view its response. Though simple, this function is often extremely beneficial when you are probing a tentative vulnerability and need to reissue the same request manually several times, tweaking elements of the request to determine the … Read more
After the essential web browser, the most useful item in your toolkit when attacking a web application is an intercepting proxy. In the early days of web applications, the intercepting proxy was a standalone tool that provided the barest of possible functionality — notably the venerable Achilles proxy, which simply displayed each request and response … Read more
