XML external entity (XXE) injection - PortSwigger In this section, we'll explain what XML external entity injection is, describe some common examples, explain how to find and exploit various kinds of XXE injection, and summarize how to prevent XXE injection attacks
What is a blind XXE attack? Tutorial Examples - PortSwigger This XXE payload declares an XML parameter entity called xxe and then uses the entity within the DTD This will cause a DNS lookup and HTTP request to the attacker's domain, verifying that the attack was successful
XXE injection - PortSwigger XML external entity injection (also known as XXE) is a web security vulnerability that allows an attacker to interfere with an application's processing of XML data
Lab: Exploiting XXE to perform SSRF attacks - PortSwigger This endpoint can be used to retrieve data about the instance, some of which might be sensitive To solve the lab, exploit the XXE vulnerability to perform an SSRF attack that obtains the server's IAM secret access key from the EC2 metadata endpoint
Testing for XXE injection vulnerabilities with Burp Suite XML external entity injection (also known as XXE) is a web security vulnerability that allows an attacker to interfere with an application's processing of XML data It occurs when user input that contains a reference to an defined external entity is processed in an unsafe way on the server-side
Lab: Exploiting XInclude to retrieve files | Web Security Academy Because you don't control the entire XML document you can't define a DTD to launch a classic XXE attack To solve the lab, inject an XInclude statement to retrieve the contents of the etc passwd file
