Discovering PHP Vulnerabilities Via Code Auditing
Abstract: PHP provides an accessible, easy to use platform for developing dynamic web applications. As the number of web based applications grow, so too does the threat from external attackers. The open and global nature of the web means that web applications are exposed to attack from around the world around the clock. Automated web application vulnerability scanning technology is still very much in its infancy, and unable to identify complex vulnerabilities that could lead to complete server compromise. While intrusion detection systems prove very valuable in detecting attacks, the best way to prevent vulnerabilities is to engage in active code review. There are many advantages of direct code review over automated testing, from the ability to identify complex edge scenario vulnerabilities to finding non-exploitable flaws and fixing them proactively. Many vulnerabilities in PHP based web applications are introduced with common misuse of the language or misunderstanding of how functions can be safely utilized. By understanding the common ways in which vulnerabilities are introduced into PHP code it becomes easy to quickly and accurately review PHP code and identify problems. In addition to common problems, PHP includes some obscure functionality that can lead developers to unwittingly introduce vulnerabilities into their applications. By understanding the security implications of some common PHP functions, code reviewers can pinpoint the use of such functions in code and inspect them to ensure safety.
