Subject: CVE-2022-33140: Apache NiFi, Apache NiFi Registry: Improper
Neutralization of Command Elements in Shell User Group Provider
Severity: high
Description:
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. Apache NiFi Registry requires an authenticated user with authorization to read user groups in order to execute the command.
The resolution removes command formatting based on user-provided arguments.
This issue is being tracked as NIFI-10114
Mitigation:
Disabling the ShellUserGroupProvider mitigates the vulnerability.
