Microsoft IIS 6.0 Unsupported Version Detection

critical Nessus Plugin ID 97994
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.
