A library PDF feature never echoes command output, but carefully timed requests show consistent delays that track injected sleep-style behavior under RoE. What detection concept applies?
Select an answer to reveal the explanation.
Short Explanation
Sometimes the house does not shout back — it just takes longer to answer the door. Blind command injection can show up as timing or out-of-band clues instead of printed output. Controlled delays under RoE are a detection concept, not a free-for-all.
Full Explanation
Blind command injection may produce no in-band output while still affecting response timing or triggering out-of-band callbacks. Testers can use carefully scoped timing or OOB techniques within rules of engagement to confirm the class. Absence of echoed output does not mean absence of execution. Unrelated network-path or CT-log ideas do not explain application-layer timing correlation.
