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
High
PR
The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
Scope
S
An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality
Low
C
There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity
Low
I
Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the 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.

# Impact :
***********
WordPress TPG Business Services is vulnerable to cross-site request forgery, caused by
improper validation of user-supplied input. By persuading an authenticated user to visit
a malicious Web site, a remote attacker could send a malformed HTTP request to
perform unauthorized actions. An attacker could exploit this vulnerability to perform
cross-site scripting attacks, Web cache poisoning, and other malicious activities.
The web application does not, or can not, sufficiently verify whether a well-formed,
valid, consistent request was intentionally provided by the user who submitted the request.
When a web server is designed to receive a request from a client without any mechanism
for verifying that it was intentionally sent, then it might be possible for an attacker to trick a
client into making an unintentional request to the web server which will be treated as an
authentic request. This can be done via a URL, image load, XMLHttpRequest, etc. and
can result in exposure of data or unintended code execution.
