Vulnerability Scan Summary
Tests for Nimda Worm infected HTML files
Detailed Explanation for this Vulnerability Test
Your server appears to have been compromised by the
Nimda mass mailing worm. It uses various known IIS
vulnerabilities to compromise the server.
Anyone visiting compromised Web servers will be prompted to
download an .eml (Outlook Express) email file, which
contains the worm as an attachment.
Also, the worm will create open network shares on the infected
computer, allowing access to the system. During this process
the worm creates the guest account with Administrator rights.
Solution: Take this server offline immediately, rebuild it and
apply ALL vendor patches and security updates before reconnecting
server to the internet, as well as security settings discussed in
Additional Information section of Microsoft's web site at
http://www.microsoft.com/technet/security/bulletin/ms01-044.mspx

Note: this worm has already infected more than 500,000 computers
worldwide since its release in late 2001.
