Manual Testing
* Identify Vulnerable Actions : Focus on actions that have significant consequences, such as:
* Fund transfers
* Password changes
* Account deletions
* Order cancellations
* Administrative actions
* Craft Malicious Requests : Try to create malicious requests that mimic the legitimate requests for these actions. You can:
* Use a simple HTML page : Create an HTML page with a hidden form that submits a request to the vulnerable action.
* Use browser extensions : Some browser extensions can be used to intercept and modify HTTP requests.
* Test with an Authenticated Session : Ensure you are logged in to the website with a valid user account before submitting the malicious request.
Automated Tools
* OWASP Zed Attack Proxy (ZAP) : A popular open-source web application security tool that includes features for detecting CSRF vulnerabilities.
* Burp Suite : A commercial web application security tool with advanced features for manual and automated security testing, including CSRF detection.
Important Considerations :
* Thorough Testing : Test all critical functionalities of the web application.
* Context : Consider the context of the application and the potential impact of a successful CSRF attack.
* False Positives : Be aware of potential false positives and carefully analyze the results of automated testing.
Example : Let's say a website has a "Change Password" feature. To test for CSRF vulnerability:
1. Create a simple HTML page :
<form action="https://[website_url]/change_password" method="POST">
<input type="hidden" name="new_password" value="new_password">
<input type="submit" value="Submit">
</form>?
2. Open the HTML page in your browser while logged in to the website.3. Observe the result : If the password is successfully changed without your explicit interaction, a CSRF vulnerability exists.
