• RIPS is a tool written in PHP to find vulnerabilities in PHP applications using static code analysis. By tokenizing and parsing all source code files RIPS is able to transform PHP source code into a program model and to detect sensitive sinks (potentially vulnerable functions) that can be tainted by userinput (influenced by a malicious user) during the program flow. Besides the structured output of found vulnerabilities RIPS also offers an integrated code audit framework for further manual analysis. http://rips-scanner.sourceforge.net/
• Vega is a free and open source scanner and testing platform to test the security of web applications.
