CRLFsuite is a powerful and efficient CRLF injection (HTTP Response Splitting) scanner designed for detecting and exploiting CRLF vulnerabilities in web applications.
The most powerful CRLF injection (HTTP Response Splitting) scanner.
This tool is primarily used by security researchers and penetration testers to identify and exploit CRLF injection vulnerabilities in web applications, which can lead to HTTP response splitting attacks. It supports scanning single or multiple URLs, making it suitable for both targeted assessments and broader security audits.
The project is no longer actively maintained by its developers, so users should be cautious about potential compatibility issues with newer environments. It is recommended to review payloads and WAF detection signatures for updates before use. The tool supports scan resumption and verbose output, which can aid in long-running assessments.
