Severity CVSS Published Added Modified
4 (AV:N/AC:M/Au:N/C:N/I:P/A:N) April 11, 2016 April 11, 2016 October 29, 2017

Description

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.
