The request is a GET to /userProfile.php with a sessionId parameter matching the JSESSIONID cookie, and the response is a 200 OK with an HTML page. Let's evaluate the statements:
* Option A ("The application uses an insecure channel (non-TLS)"):
The request uses http:// (inferred from the absence of https:// in the Host and GET line), indicating a non-TLS channel. However, the question asks about the "application" (likely the server-side behavior), and the response does not explicitly confirm the channel used for the response. Modern browsers might enforce TLS, but the request suggests an insecure channel. This could be true, but it depends on the server's configuration, making it less certain without further context.
* Option B ("The application uses an insecure HTTP method (GET) to send sensitive information")
: Correct. The sessionId parameter in the URL (/userProfile.php?
sessionId=7576572ce164646de967c759643d53031) is sensitive data, as it could be used to hijack the user's session. Using GET exposes this data in browser history, server logs, and referral headers, which is insecure. Best practice is to use POST for sensitive data to avoid such exposure. The JSESSIONID cookie is marked HttpOnly, mitigating some risks, but the sessionId in the URL remains a vulnerability.
* Option C ("The application is vulnerable to Cross-Site Scripting attacks"): The response includes an HTML page with no visible user input or script execution. There's no evidence of unsanitized input or script injection (e.g., no dynamic content like <script> tags with user data). The X-Xss-Protection: 1; mode=block header (though not shown) would mitigate XSS if present, but the response alone does not indicate vulnerability, so this is incorrect.
* Option D ("All of the above"): Incorrect, as only B is definitively true; A is uncertain without confirming the response channel, and C lacks evidence.
The correct answer is B, aligning with the CAP syllabus under "HTTP Methods Security" and "Session Management."References: SecOps Group CAP Documents - "Insecure HTTP Methods," "Sensitive Data Exposure," and "OWASP Secure Coding Practices" sections.
