CORStest
CORStest is a security scanning tool designed to identify Cross-Origin Resource Sharing (CORS) misconfigurations in web applications. The tool analyzes CORS policies implemented by web servers and identifies potential security vulnerabilities that could allow unauthorized cross-origin requests. It examines HTTP response headers related to CORS configuration, including Access-Control-Allow-Origin, Access-Control-Allow-Methods, and other CORS-related headers. CORStest helps security professionals and developers detect common CORS misconfigurations such as overly permissive wildcard origins, improper credential handling, and inadequate access controls that could expose applications to cross-site request forgery attacks and data theft. The scanner provides straightforward functionality for testing individual URLs or domains to assess their CORS implementation and identify potential security risks associated with cross-origin resource sharing policies.
