A somewhat curated list of links to information about XML External Entity (XXE).

An XML External Entity attack is a type of attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts.

11.2 Lab: Exploiting XXE to perform SSRF attacks | 2023This lab has a “Check stock” feature that parses XML input and returns any unexpected values in the response. The lab server is running a (simulated) EC2 metadata endpoint at the default URL, which is http://169.254.169.254/.

XXE attacks 😈XML is probably the most commonly used markup language. It’s organized around tags <example>foo</example> and allows pretty complicated structures One interesting property about XML is that you can reference external entities, e.g. you can include another file.
XXE – Things Are Getting Out of BandThis isn’t anything new however has been a long time in writing as I’ve been playing around with things! It is more my take on how to do these types of attacks and how I’ve found different tools to be better than others alongside different techniques being more efficient and generally better.
XXE - XEE - XML External EntityAn XML External Entity attack is a type of attack against an application that parses XML input. XML stands for "extensible markup language". XML is a language designed for storing and transporting data. Like HTML, XML uses a tree-like structure of tags and data.
From blind XXE to root-level file read accessOn a recent bug bounty adventure, I came across an XML endpoint that responded interestingly to attempted XXE exploitation. The endpoint was largely undocumented, and the only reference to it that I could find was an early 2016 post from a distraught developer in difficulties.
