How to fix?

Upgrade com.zaxxer:nuprocess to version 2.0.5 or higher.

Overview

Affected versions of this package are vulnerable to Arbitrary Command Injection due to improper user-input sanitization, allowing attackers to use NUL characters in their strings in order to craft a malicious payload.

** Note: ** Java's ProcessBuilder isn't vulnerable because of a check in ProcessBuilder.start. NuProcess is missing that check.

This vulnerability can only be exploited to inject command line arguments on Linux.

Workaround:

Users who are unable to upgrade to the fixed version can sanitize command strings to remove NUL characters prior to passing them to NuProcess for execution.
