Last modified

CVE-2016-2114 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.60% chance of exploitation in the next 30 days.
