Script Summary

Attempts to detect if a Microsoft SMBv1 server is vulnerable to a remote code execution vulnerability (ms17-010, a.k.a. EternalBlue). The vulnerability is actively exploited by WannaCry and Petya ransomware and other malware.

The script connects to the $IPC tree, executes a transaction on FID 0 and checks if the error "STATUS_INSUFF_SERVER_RESOURCES" is returned to determine if the target is not patched against ms17-010. Additionally it checks for known error codes returned by patched systems.

Tested on Windows XP, 2003, 7, 8, 8.1, 10, 2008, 2012 and 2016.
