Authenticated code execution via arbitrary Spring bean invocation
Published Apr 19, 2025 · Updated Apr 21, 2025
Command injection in CicadasCMS 2.0 allows remote authenticated users to invoke arbitrary Spring bean methods through scheduled tasks. The save handler accepts attacker-controlled springBean and methodName values, and the task runner resolves that bean and invokes the named method without an execution allowlist. High-privilege access to the scheduled-task interface is required; the published proof demonstrates disruption of scheduled-task execution.
