AirBorne: Wormable zero-click remote code execution (RCE) in AirPlay protocol
- throw0101a 1y agoCVE-2025-24252 and CVE-2025-24132 are two examples. Doing a search for "Oligo" in release notes gives various other results, e.g., * https://support.apple.com/en-ca/122374 https://support.apple.com/en-ca/122374 Apple fixed their stuff, but third-parties who used their SDK will have to issue updates as well.
- john_alan 1y agoHeya, is it possible to detect the worm on iOS / macOS? Does the fix in latest OS just remove the worm if unknowingly infected? Reads like a zero click infection leading to arbitrary execution of long running code. Seems fairly insidious?
- abhisek 1y agoVery curious about the exploitation of CVE-2025-24252, a use-after-free (UAF) using which they achieved zero-click RCE on MacOS. This is inspite of ASLR and heap exploitation mitigations in place to mitigate such vulnerability classes https://security.apple.com/blog/towards-the-next-generation-of-xnu-memory-safety/ https://security.apple.com/blog/towards-the-next-generation-...
- hammock 1y agoOn ASLR: you might use the UAF to access memory regions you shouldn’t have access to. By reading the contents, they can potentially leak pointers to a critical library (e.g., libc), allowing them to calculate the offsets to bypass ASLR. On heap protection: if you spray the heap with predictable data patterns you can improve your chance of landing a useful address, even with ASLR in place
- RainyDayTmrw 1y agoI understand heap sprays in theory. In practice, how do they avoid clobbering something important and crashing the app? It seems like a typical app has a lot of state to clobber.

- xyzzy123 1y agoThe writes for a spray are pre exploit, you are going through an allocator to get the space you're writing to. Put another way, its the apps job to write the spray into "free space". Sprays are pretty crashy but the heap setup is not usually the problem, its that the pointer you want to control "missed" the sprayed area.

- rubatuga 1y agoGood thing I'm still on macOS 12
- slama 1y agomacOS 12 is EOL and is no longer receiving security updates. There’s a strong chance it’s vulnerable, too
- m463 1y agomacos is pretty promiscuous, and I've noticed random airplay displays (like the neighbors) showing up in the mirroring dropdown in the dock. wonder if this is a way to get into the stack.
- greyadept 1y agoThis behaviour always made me feel a bit suspicious about airplay but I reassured myself that Apple surely had it locked down. But these 17 CVEs show that my trust was misplaced.
- Roguelazer 1y agoRunning a parser for a network protocol as root seems like a pretty unnecessarily dumb thing to do. I can't really imagine why any part of airplay would need to run as root; maybe something to do with DRM? Although the DRM daemon `fairplayd` runs as a limited-privilege user `_fpsd`, so maybe not. So bizarre that Apple makes all these cool systems to sandbox code, and creates dozens of privilege-separated users on macOS, and then runs an HTTP server doing plists parsing as an unsandboxed root process.
- Mindwipe 1y agoApple have reworked Airplay so many times at this point the entire thing is just a massive pile of technical debt piled on another massive pile of technical debt, piled on a bunch of weird hacks to try and keep all the devices built for previous versions afloat.
- walterbell 1y agoAt least it can be disabled via MDM/Configurator policy.
- bigyabai 1y agoTo the express benefit of all 3 Apple users that configure their devices with a PList editor.
- walterbell 1y agoThe breaches will continue until device policy improves.
- bigyabai 1y agoThree cheers for smart defaults!

- RainyDayTmrw 1y agoOof. It's parsing and memory corruption again.
- pjmlp 1y agoBasically a collection of use-after-free, stack-based buffer overflow, type confusion, memory exhaustion, integer overflow, NULL pointer dereference, for the most part. However we all know that the problem is that juniors and interns are the ones that get to write this code, a senior with proper education would never deliver these mistakes into production. /s
