route-detect

Web application HTTP route authentication (authn) and authorization (authz) bugs are some of the most common security issues found today. These industry standard resources highlight the severity of the issue:

• 2021 OWASP Top 10 #1 - Broken Access Control
• 2021 OWASP Top 10 #7 - Identification and Authentication Failures (formerly Broken Authentication)
• 2019 OWASP API Top 10 #2 - Broken User Authentication
• 2019 OWASP API Top 10 #5 - Broken Function Level Authorization
• 2022 CWE Top 25 #14 - CWE-287: Improper Authentication
• 2022 CWE Top 25 #16 - CWE-862: Missing Authorization
• 2022 CWE Top 25 #18 - CWE-306: Missing Authentication for Critical Function
• #21 most CVEs by CWE - CWE-284: Access Control (Authorization) Issues
• #47 most CVEs by CWE - CWE-639: Access Control Bypass Through User-Controlled Key

Of course, not all authn and authz bugs are due to route issues, but route-detect seeks to automate detection of this vulnerability subclass.

route-detect uses semgrep to search for routes.

Use the which command to point semgrep at the correct web application rules:

$ semgrep --config $(routes which django) path/to/django/code

Use the viz command to visualize route information in your browser:

$ semgrep --json --config $(routes which django) path/to/django/code > routes.json
$ routes viz --browser routes.json
