CVE-2024-29831Network attack vector

Authenticated code execution via Switch condition evaluation

Published Aug 9, 2024 · Updated Aug 12, 2024

Improper input validation in Apache DolphinScheduler before 3.2.2 allows remote authenticated users to execute code through Switch tasks. SwitchTaskUtils substitutes task parameters into a condition and passes the result to an unsandboxed JavaScript engine without rejecting dangerous language features. An authenticated user who can define and run a Switch task can invoke Java runtime APIs to execute server-side commands with the scheduler process privileges.
