Question
Which is an attack against an application that parses XML input?
- Injection
- XXE
- Input validation
Solution
The attack against an application that parses XML input is called XXE (XML External Entity) Injection. This type of attack exploits a vulnerability in the application's processing of XML input, allowing an attacker to interfere with the application's XML parsing and potentially gain unauthorized access to data.
Here are the steps of how it works:
-
The attacker sends malicious XML input to the application. This input includes a reference to an external entity, which is a URI that the XML parser will attempt to access and incorporate into the parsed XML document.
-
If the application is vulnerable to XXE injection, it will attempt to access the URI specified by the external entity. This could lead to various harmful outcomes, such as disclosure of confidential data, denial of service, or server-side request forgery.
-
To prevent XXE injection, applications should disable the use of external entities in their XML parsers. Additionally, they should use input validation to ensure that incoming XML documents do not contain unexpected constructs.
