You could use the 404 CSS error to check if the server has the patch
installed. Make a request for some non-existant page, e.g.
http://YOUR.TLD/3lkb54j6b4kjb6jk456bk45bk45jb, then read line 42 and
compare.
Not patched line 42:
document.write( '<A HREF="' + escape(urlresult) + '">' +
displayresult + "</a>");
Patched line 42:
InsertElementAnchor(urlresult, displayresult);
Custom 404 page: Anything else. If they bothered to make a custom 404 page,
they probably also bothered to apply critical patches as this one.
This is all demonstrated at http://jscript.dk/adv/TL001/, where a quick
survey of the "Simple" examples show that hotmail.msn.com, passport.com and
lc2.law5.hotmail.passport.com are still unpatched. You may get different
results from testing, as they most likely run in a cluster.
