Vulnerability Information

Severity: Critical
Vulnerability Published: 2017-06-21
Patch Published: 2017-06-21
CVE [?]: CVE-2017-6324, CVE-2017-6325, CVE-2017-6326
CPE [?]: cpe:/a:symantec:messaging_gateway

Synopsis

A messaging security application running on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Symantec Messaging Gateway (SMG) running on the remote host is 10.x prior to 10.6.3-266. It is, therefore, affected by multiple vulnerabilities :

- A security feature bypass vulnerability exists when handling email attachments involving malformed or corrupted Word files containing macros. An unauthenticated, remote attacker can exploit this, via a specially crafted email, to bypass the 'disarm' functionality even though it has been enabled by the administrator. (CVE-2017-6324)

- A local file inclusion vulnerability exists due to a failure to properly sanitize user-supplied input when building a path to executable code. An authenticated, remote attacker can exploit this, via a specially crafted request, to include arbitrary files for execution, provided they are already present on the targeted host. (CVE-2017-6325)

- An unspecified flaw exists that allows an authenticated, remote attacker to execute arbitrary code. (CVE-2017-6326)

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

Solution

Upgrade to Symantec Messaging Gateway (SMG) version 10.6.3-266 or later.
