Exam CS0-003 topic 1 question 17 discussion

I was originally going to go with B, but the syntax of the parameter is incorrect at the end (has id-2 and not id=2) which negated this choice as a potentially valid answer. This would make D the only viable correct answer.

This was specifically an XSS (Cross-Site Scripting) scan, as mentioned in the introduction The script "http-unsafe-output-escaping" was used, which specifically tests for reflected XSS vulnerabilities The characters > and " were successfully injected into the parameter These characters are particularly significant in XSS attacks as they can be used to break out of HTML tags and attributes Answer D is indeed the most accurate because: D. The vulnerable parameter and characters > and " with a reflected XSS attempt This option correctly identifies: There is a vulnerable parameter (id) The specific characters > and " were tested Most importantly, it specifically mentions this was a "reflected XSS attempt" - which aligns with the purpose of the scan Option C mentions "unfiltered or encoded characters" but misses the critical point that this was specifically testing for reflected XSS vulnerability, which is the main purpose of this particular Nmap script.

Answer C focuses on identifying the vulnerability and the unsafe handling of characters, but does not go as far as to indicate an active exploit attempt. It’s more about describing the vulnerability itself. Answer D goes further by implying that the unfiltered characters (>, ") are part of a reflected XSS attack, indicating that the vulnerability has been or can be actively exploited.
