CVE-2016-2115

CVSS v3.1

5.9

Medium

VectorAV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
Name of the Vulnerable Software and Affected Versions Samba versions 3.x and earlier Samba versions 4.1.x through 4.2.10 Samba versions 4.3.x through 4.3.7 Samba versions 4.4.x through 4.4.1
Description The issue is related to the lack of required SMB signing within a DCERPC session over ncacn np, allowing man-in-the-middle attackers to spoof SMB clients by modifying the client-server data stream. This vulnerability is associated with security shortcomings in the ncacn np function of the Samba network interaction package, which can be exploited by a remote attacker to impact data integrity.
Recommendations For Samba versions 3.x and earlier, update to version 4.2.11 or later. For Samba versions 4.1.x through 4.2.10, update to version 4.2.11 or later. For Samba versions 4.3.x through 4.3.7, update to version 4.3.8 or later. For Samba versions 4.4.x through 4.4.1, update to version 4.4.2 or later.
