Hundreds of Thousands of Web Servers have been getting hacked, including several at the United Nations. The appearance is that the hack exploits a vulnerability in Microsoft IIS because of a Microsoft SQL Specific injection payload, however the attack is capable of infecting any type of web server open to SQL Injection and Cross Site Scriting (XSS) attacks.
Microsoft released some security bulletins (951306, MS08-006) stating vulnerabilities in their IIS web server, alluding to the vulnerabilities recently brought to light. A script homed at nihaorr1.com based in China was found to be infecting many servers, and spreading quickly. Further research into the problem indicates that non-Microsoft types of servers may also be affected by the attack.
This vulnerability and others like it can easily be stopped with a Citrix Web Application Firewall using default policies to block SQL injection and Cross Site Scripting. We setup a demo in our lab, to show how easy it is to configure and block this type of threat.
