We recently released fixes for the publicly disclosed FTP vulnerabilities. One of the after-effects of applying this update will be that recursive list commands to IIS FTP 5.x, 6.0 will return the non-recursive listing. To make it clear, this feature does not exist on IIS FTP 7.x either, and that is why I did not include those versions in the previous statement. For those that will miss this feature, there is a workaround on Robert McMurray’s blog.
Microsoft has released security bulletin MS09-053 that will address the FTP vulnerabilities that were publicly disclosed a couple of weeks ago. The information in this bulletin supercedes the previous advisory.
