Vulnerability details

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, an authenticated command injection vulnerability in the Destination Network Management functionality allows users with destination management permissions to execute arbitrary commands as root on…

Why these techniques?

Authenticated command injection (CWE-78) in Coolify directly enables RCE via unsanitized shell input, mapping to exploitation of a public-facing management app (T1190) and Unix shell command execution (T1059.004).

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
