Technical details

An OS command injection vulnerability exists in Budibase's bash automation step within 'packages/server/src/automations/steps/bash.ts'. The application uses 'execSync' to run user-provided code after processing it through 'processStringSync', which supports template interpolation. Because the input is not properly sanitized or validated, an attacker with 'low' privileges (sufficient to create or modify automations) can inject malicious shell commands using standard syntax like $(command) or command chaining. This results in remote code execution (RCE) on the host system. The vulnerability is addressed in version 3.33.4 by implementing command validation and switching to safer execution methods.
