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.

[#] Technical Details & Description:
====================================
Insecure File Permissions vulnerability has been discovered in the official WampServer v3.0.6 software.
The vulnerability exists due to insecure default permissions set on the Allok Video to 'iPod Converter.exe' and 'avep.exe' or 'unins000.exe'
A local attacker could exploit this vulnerability by replacing 'iPod Converter.exe' and 'avep.exe' or 'unins000.exe' with a malicious executable file.
The malicious file could execute or modify with the LocalSystem permissions.
Proof of Concept (PoC):
=======================
Allock Video to Ipod converter for Windows contains a vulnerability that could allow a local attacker to gain elevated privileges.
