Man-in-the-Middle (MitM)

samba is vulnerable to man-in-the-middle (MitM) attacks. The vulnerability exists as it was found that samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8 did not enforce “SMB signing” when certain configuration options were enabled. A remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text.
