Samba 4.9.x < 4.9.13 / 4.10.x < 4.10.8 / 4.11.0rc3 Security Bypass (CVE-2019-10197)

critical Nessus Plugin ID 128549

Language:

Synopsis

The remote Samba server is potentially affected by a man in the middle vulnerability.

Description

The version of Samba running on the remote host is 4.9.x prior to 4.9.13, 4.10.x prior to 4.10.3.8, or 4.11.x prior to 4.11.0rc3. It is, therefore, affected by security bypass vulnerability.
An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share.

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 4.9.13 / 4.10.8 / 4.11.0rc3 or later.
