Samba 4.9.x < 4.9.6 / 4.10.0 < 4.10.2 World-Writable Files Vulnerability (CVE-2019-3870)

medium Nessus Plugin ID 124087

Language:

Synopsis

The remote Samba server is potentially affected by a world writable files vulnerability.

Description

The version of Samba running on the remote host is 4.9.x < 4.9.6 or 4.10.0 prior to 4.10.2. It is, therefore, potentially affected by a world writable files vulnerability. An authenticated, local attacker can exploit this issue to read and update files in the private/ directory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Samba version 4.9.6 / 4.10.2 or later.
