WHAT IT DOES

What run_impacket_tstool does on Pentester-MCP

AI agents invoke run_impacket_tstool to trigger actions in Pentester-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why run_impacket_tstool is rated High

This tool executes a penetration testing utility that manipulates authentication credentials and Kerberos tickets. This falls squarely into the Execute category—it runs external code/tools whose effects depend on how an AI agent invokes it (which tickets to forge, which systems to target, etc.).

From the tool's definition Tool name 'run_impacket_tstool' references impacket's tstool, a component for manipulating Kerberos tickets and authentication tokens.
