Technical details

A remote code execution vulnerability exists in Claris FileMaker Cloud due to improper validation of OS Script schedule types. An attacker with valid Admin Console privileges can bypass front-end restrictions to inject and execute arbitrary operating system commands on the underlying host. This is classified as a code injection (CWE-94) issue where the application fails to properly neutralize or restrict command execution to intended functions. The attack requires high privileges (Admin Console access) but can be executed over the network without user interaction. The issue is addressed in FileMaker Cloud version 2.22.0.5.
