Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 13.2%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
