Samba CVE-2016-2114: "server signing = mandatory" not enforced

Severity CVSS Published Added Modified
4 (AV:N/AC:M/Au:N/C:N/I:P/A:N) April 12, 2016 April 12, 2016 May 04, 2018

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.
