The OWASP Benchmark Project is a Java test suite designed to verify the speed and accuracy of vulnerability detection tools. The initial version is intended to support Static Analysis Security Testing Tools (SAST). A future release will support Dynamic Analysis Security Testing Tools (DAST), like OWASP ZAP, and Interactive Analysis Security Testing Tools (IAST). The goal is that this test application is fully runnable and all the vulnerabilities are actually exploitable so its a fair test for any kind of application vulnerability detection tool.
The project documentation is all on the OWASP site at the OWASP Benchmark project pages. Please refer to that site for all the project details.
The current latest release is v1.2. Note that all the releases that are available here: https://github.com/OWASP/Benchmark/releases, are historical. The latest release is always available live by simply cloning or pulling the head of this repository (i.e., git pull).
