Microsoft Windows SMBv1 SMB COM NT TRANSACT Total Data Count Buffer Overflow

This strike recreates a buffer overflow attack in Microsoft Windows SMBv1 service. The vulnerability is due to insufficient sanitization of user-supplied input while processing SMB COM NT TRANSACT requests. A remote, unauthenticated attacker could exploit this vulnerability via a specially-crafted SMB packet, containing a bad value for SizeOfListInBytes for the specified SMB package type. Successful exploitation leads to arbitrary code execution on the target system. * NOTE: This vulnerability was targeted with ShadowBrokers EternalBlue exploit.
