What is XML injection and how does it work?

XML injection is a type of attack where an attacker inserts malicious XML code into a web application's XML data. This can manipulate the application's behavior or extract sensitive information.

Can you give me an example of how an XML injection attack might be executed?

Sure! For instance, if a web application accepts XML input without proper validation, an attacker might send a payload like: <user><name>John</name><role>admin</role></user>. This could escalate their privileges if the application processes it without checks.

What are some ways to prevent XML injection attacks?

To prevent XML injection, you should validate and sanitize all XML inputs, use parameterized queries, and implement strict access controls.

Are there any tools available to test for XML injection vulnerabilities?

Yes, there are several tools like Burp Suite, OWASP ZAP, and XML Security Library that can help identify XML injection vulnerabilities.
