Samba 3.x < 3.6.20 / 4.0.x < 4.0.11 / 4.1.x < 4.1.1 Multiple Vulnerabilities

medium Nessus Plugin ID 70926
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Samba server is affected by multiple vulnerabilities.

Description

According to its banner, the version of Samba running on the remote host is 3.x prior to 3.6.20 or 4.0.x prior to 4.0.11 or 4.1.x prior to 4.1.1. It is, therefore, potentially affected by multiple vulnerabilities :

- A security bypass vulnerability may exist because Samba does not properly enforce ACL restrictions when accessing alternate data streams. Either the 'vfs_streams_depot' or 'vfs_stream_xattr' module must be enabled for the host to be vulnerable.
(CVE-2013-4475)

- Sensitive information may be obtained because the private key used for SSL/TLS encryption is readable by any local user. Note that this only applies to versions 4.0.x prior to 4.0.11 and 4.1.0.
(CVE-2013-4476)

Further note that Nessus has relied only on the self-reported version number and has not actually tried to exploit this issue or determine if the associated patch has been applied.

Solution

Upgrade to version 3.6.20 / 4.0.11 / 4.1.1 or later or refer to the vendor for a patch or workaround.
