OS Command Injection in Foreman foreman-tail Utility

Executive Summary

This is a command injection vulnerability in Foreman's foreman-tail utility. It occurs because the script uses the eval command unsafely, directly incorporating user input into a string that gets executed. Without proper sanitization or quoting, attackers can inject shell metacharacters like semicolons or pipes to run arbitrary system commands.
