Authenticated camera hijacking via malicious dylib
Published Nov 2, 2021 · Updated Oct 25, 2024
Improper code generation in FortiClient macOS 7.0.0 and earlier and 6.4.5 and earlier lets remote authenticated users hijack the macOS camera. The flaw loads a malicious dylib through an improperly controlled code-generation path, bypassing the normal camera permission check. An authenticated attacker with local execution context and user interaction can obtain camera video; the record does not report broader data access or service disruption.
