Mô tả CAPEC
An adversary may execute a flooding attack using XML messages with the intent to deny legitimate users access to a web service. These attacks are accomplished by sending a large number of XML based requests and letting the service attempt to parse each one. In many cases this type of an attack will result in a XML Denial of Service (XDoS) due to an application becoming unstable, freezing, or crashing.

An adversary crafts input data that may have an adverse effect on the operation of the web service when the XML data sent to the service.
3) Exploit
[Launch a resource depletion attack] The attacker delivers a large number of XML messages to the target URLs found in the explore phase at a sufficiently rapid rate. It causes denial of service to the target application.
Kỹ thuật
- Send a large number of crafted XML messages to the target URL.
Điều kiện tiên quyết
The target must receive and process XML transactions.An adverssary must possess the ability to generate a large amount of XML based messages to send to the target service.
Kỹ năng cần thiết
Denial of serviceCác biện pháp giảm thiểu
Design: Build throttling mechanism into the resource allocation. Provide for a timeout mechanism for allocated resources whose transaction does not complete within a specified interval.Implementation: Provide for network flow control and traffic shaping to control access to the resources.
