In today’s digital landscape, web application security is paramount. One vulnerability that often
flies under the radar but can have severe consequences is XML External Entity (XXE) injection.
This article will explore XXE injection, its potential impacts, and how to protect against it.
What is XXE Injection?
XXE injection is a web security vulnerability that occurs when an application processes XML
input without proper safeguards. It allows attackers to interfere with the application’s XML data
processing, potentially leading to
What is XXE Injection?
XXE injection is a web security vulnerability that occurs when an application processes XML
input without proper safeguards. It allows attackers to interfere with the application’s XML data
processing, potentially leading to:
- Unauthorized access to sensitive files on the server
- Interaction with back-end systems
- Server-side request forgery (SSRF) attacks
How XXE Vulnerabilities Arise
XXE vulnerabilities typically emerge when applications use XML to transmit data between the
browser and server. The XML specification includes potentially dangerous features that
standard parsers support by default, even if the application doesn’t use them.
How XXE Vulnerabilities Arise
- File Retrieval: Attackers define an external entity containing file contents and return it in the application’s response.
- SSRF Attacks: External entities are defined based on URLs to back-end systems.
- Blind XXE Data Exfiltration: Sensitive data is transmitted out-of-band to attacker-controlled systems.
- Error-Based Data Retrieval: Attackers trigger parsing errors containing sensitive
information
