In this series, we take a look at Web Security Academy's External Entity Injection lab and break it down. The goal is to break down the concepts to not only get to the solution, but talk about methodology and the mental steps we take in order to discover these vulnerabilities in the wild.

Lab 1: Exploiting XXE using external entities to retrieve files
Lab 2: Exploiting XXE to perform SSRF attacks
Lab 3: Blind XXE with out-of-band interaction
Lab 4: Blind XXE with out-of-band interaction via XML parameter entities
Lab 5: Exploiting blind XXE to exfiltrate data using a malicious external DTD
