Microsoft IIS 6.0 Unsupported Version Detection

critical Nessus Plugin ID 97994


An unsupported version of Microsoft IIS is running on the remote Windows host.


According to its self-reported version number, the installation of Microsoft Internet Information Services (IIS) 6.0 on the remote host is no longer supported.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.


Upgrade to a version of Microsoft IIS that is currently supported.
