Miggo AIRoot Cause Analysis

The vulnerability description explicitly identifies the execute() function's arrParams argument as the injection vector. The code shows arrParams.join(' ') being directly interpolated into a system command string executed via exec(). There's no input validation or sanitization visible in the code path from user input to command execution. The combination of untrusted input concatenation with exec() creates a classic OS command injection scenario (CWE-78).
