Blind XXE Attack
A Blind XXE Attack is a type of cyber attack that can happen when a web application doesn’t properly protect against XXE (XML External Entity) vulnerabilities. Basically, when an attacker sends a specially crafted XML file to the web application, it can cause the application to carry out unwanted actions without the user’s knowledge.
Here’s an easy way to think about it: Imagine you’re playing a game and your friend sends you a message that says, “Type this code into the game to unlock a secret level!” But when you type in the code, it actually causes the game to delete all of your progress instead. That’s kind of like a Blind XXE Attack!
Even though you didn’t know it at the time, the code your friend gave you had a hidden message inside that caused the game to do something bad. In the same way, an attacker can hide malicious code inside an XML file and send it to a vulnerable web application, causing it to carry out unwanted actions without the user’s knowledge. This could include things like deleting files or stealing sensitive information.
