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.
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
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

# Impact :
***********
WordPress DailyDeal Themes is prone to a vulnerability that lets attackers
upload arbitrary files because it fails to adequately sanitize user-supplied input.
An attacker can exploit this vulnerability to upload arbitrary code and execute
it in the context of the webserver process. This may facilitate unauthorized access
or privilege escalation; other attacks are also possible.
CWE-352: Cross-Site Request Forgery (CSRF)
******************************************
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.
CWE-264: Permissions, Privileges, and Access Controls
**************************************************
Weaknesses in this category are related to the management of permissions, privileges, and
other security features that are used to perform access control.
CWE-434: Unrestricted Upload of File with Dangerous Type
****************************************************
The software allows the attacker to upload or transfer files of dangerous types that can
be automatically processed within the product's environment.
