Question 40
During a planned service expansion at Maple Creek Agriculture, engineers say that they resolved this finding: A cookie-authenticated application accepts an account change request from another origin without an anti-forgery check. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
A forged cross-origin request is rejected while the legitimate authenticated workflow succeeds. This is the decisive evidence for the original problem: A cookie-authenticated application accepts an account change request from another origin without an anti-forgery check. It verifies that the intended corrective control—Require CSRF protection and validate origin and same-site cookie policy for state-changing operations—works in the relevant environment; a completed change ticket alone would not prove the outcome at Maple Creek Agriculture.
Incorrect Answers
Encoded and plain traversal probes cannot read files outside the approved directory. This would be relevant evidence for a different failure: A web service builds filesystem paths directly from user-controlled filenames so clients can request parent directories, usually addressed by Normalize and restrict paths to an authorized root and deny traversal outside the allowed file set. It does not demonstrate that the current problem at Maple Creek Agriculture was resolved. The specific required evidence is: A forged cross-origin request is rejected while the legitimate authenticated workflow succeeds.
Asset inventory and version checks show the affected vulnerable component was remediated. This would be relevant evidence for a different failure: An appliance runs software with a published high-impact CVE that affects its exposed management interface, usually addressed by Validate the product-specific advisory and remediate according to exposure and severity using an approved patch window. It does not demonstrate that the current problem at Maple Creek Agriculture was resolved. The specific required evidence is: A forged cross-origin request is rejected while the legitimate authenticated workflow succeeds.
Stored and reflected script payloads display as text without execution. This would be relevant evidence for a different failure: An app reflects untrusted user comments as executable markup in the browser, usually addressed by Encode output for its HTML context and enforce appropriate browser content restrictions. It does not demonstrate that the current problem at Maple Creek Agriculture was resolved. The specific required evidence is: A forged cross-origin request is rejected while the legitimate authenticated workflow succeeds.
