CVE-2022-33140 – Improper Neutralization of Command Elements in Shell User Group Provider

https://notcve.org/view.php?id=CVE-2022-33140

The optional ShellUserGroupProvider in Apache NiFi 1.10.0 to 1.16.2 and Apache NiFi Registry 0.6.0 to 1.16.2 does not neutralize arguments for group resolution commands, allowing injection of operating system commands on Linux and macOS platforms. The ShellUserGroupProvider is not included in the default configuration. Command injection requires ShellUserGroupProvider to be one of the enabled User Group Providers in the Authorizers configuration. Command injection also requires an authenticated user with elevated privileges. Apache NiFi requires an authenticated user with authorization to modify access policies in order to execute the command. • https://lists.apache.org/thread/bzs2pcdjsdrh5039oslmfr9mbs9qqdhr https://nifi.apache.org/security.html#CVE-2022-33140 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
