Payload 8.8.8.8; sleep 5. Status 200. Response time jumped from ~800ms to ~6s. The scanner wrote OS command injection, confidence high. The client had already seen the word critical in the draft.I replayed it once. Same delay. Replay again. 1.1s. Again. 7s. Again. 900ms.

It echoed the query and, under load, the WAF in front of it spent extra time on anything that looked like a shell metacharacter.That is a known failure mode, not a rare one. Time-based command-injection checks fire when the response is merely slower, which also happens when the scanRedditFrom the netsec community on RedditExplore this post and more from the netsec communityNetsec
