Описание
The SMB1 protocol implementation in Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "server signing = mandatory" setting, which allows man-in-the-middle attackers to spoof SMB servers by modifying the client-server data stream.
It was discovered that Samba did not enforce Server Message Block (SMB) signing for clients using the SMB1 protocol. A man-in-the-middle attacker could use this flaw to modify traffic between a client and a server.
