> Rate limiting would be performed in the Apple server itself or in HSM (hardware security module). Either way, the rate limit logic should be programmed as such to prevent race hazard. There is very bleak chance for this endpoint to be not vulnerable to race hazard before my report because all the other endpoints I tested was vulnerable
The HSMs they’re using at Apple aren’t patchable… that’s kinda the point. Sorry.
- laxmanmuthiyah 5y agoHSM is not handling the http requests directly. If you send an improper request data like not sending proper xml, you will see the errors from the iCloud server endpoint. The endpoint that is sending data to HSM could be patched to validate concurrent requests. Of course I may be missing something but we will never know the truth until Apple confirms it.
