Improper certificate validation in the PAM propagation WinRM connections
allows a network attacker to perform a man-in-the-middle attack via
disabled TLS certificate verification.
The following code is for security research and authorized testing only.
python
import winrm
# This script demonstrates the vulnerability scenario where TLS certificate validation is disabled.
# This is insecure and should only be used for educational/testing purposes against authorized targets.
def vulnerable_winrm_connection(target_host, username, password):
# Exploit: Disable server certificate verification
session = winrm.Session(
target_host,
auth=(username, password),
server_cert_validation='ignore' # VULNERABILITY: Disabled TLS certificate verification
)
# Run a command
result = session.run_cmd('hostname', [])
print(f"StdOut: {result.std_out.decode()}")
print(f"StdErr: {result.std_err.decode()}")
if __name__ == "__main__":
# Example usage (replace with actual target details during pentest)
# vulnerable_winrm_connection('https://target-pam-server:5986/wsman', 'admin', 'password')
