MS06-008 is not categorized as virus, worm, Trojan or backdoor. It is an important vulnerability in Web Client Service on Windows 2003/XP computers, which allows to remotely execute arbitrary code and to perform a local privilege escalation attack in the vulnerable computer.
If exploited successfully, MS06-008 allows hackers to carry out the following actions:
- Gain remote control of the affected computer with the same privileges as the logged on user. If this user had administrator rights , the hacker could take complete control of the system: create, modify or delete files, install programs, create new user accounts, etc.
- Gain unauthorized privileges on a computer or network. An example of privilege elevation would be an unprivileged user who could manage to be added to the Administrator's group. In such case, the hacker could take complete control of the system: create, modify or delete files, install programs, create new user accounts, etc.
This vulnerability is usually exploited directly over a computer network by creating special network packets and sending them to a vulnerable computer.
However, the attacking user must have valid logon credentials (username and password).
Attacks can be launched across the Internet, but a firewall could be used in order to prevent those attacks.
