Which term describes attacks that target the parsing stage of XML in web services to cause DoS or logic errors?

• A. Web Services Parsing Attacks
• B. Frame Injection
• C. Oversize Payloads
• D. Recursive Payloads

Answer: (A)

XML parsing attacks exploit the parser that web services use to read XML input. When the parser processes crafted XML in a way that causes excessive resource use or faulty logic, it can lead to DoS or unintended behavior. The term that best describes this whole class of threats is Web Services Parsing Attacks, because it directly references attacks happening during the XML parsing stage in web services. Frame Injection targets UI framing mechanisms rather than XML parsing, so it isn’t the right fit here. Oversize Payloads and Recursive Payloads describe specific payload strategies, with the latter often illustrating a known XML parser flaw, but they are not as broad or precise a label for the general category as Web Services Parsing Attacks. Keeping the focus on the parsing stage helps you recognize and defend against issues like dangerous entity expansion or DTD processing within XML.
