Actual exam question for XML's I10-003 exam

Question #: 56
Topic #: 6

A certain Web application displays user information according to user input via Web browser. The XML data managing user information is as shown in [example xm I] referenced in a separate window.

At this time, the Web application completes the [XQuery] by replacing (1) and (2) with the user input character string, and executes the query.

No character escapes (e.g. convert "<" to "<") are performed for character string input by the user.

Select the query execution result when the user input character string is as follows:

(1) "]/fn:root(),()/a[a="

(2) OK

Ah, the age-old dilemma: to sanitize or not to sanitize? That is the question. And the answer is, of course, to sanitize. Unless you're a fan of XML-flavored chaos, that is.

I'm going with B. I mean, who wouldn't want to see the user information displayed, right? What could possibly go wrong?

D, definitely D. An error should occur when the user input is passed directly into the XQuery without any sanitization. That's a classic security flaw waiting to happen.

Wow, this question is really tricky! I'm going to have to think about this one carefully. The lack of character escaping is definitely a concern.

I think the correct answer is C. The user input character string contains an XML tag that could be interpreted as part of the XML structure, potentially leading to a security vulnerability known as XML injection.
