_LASTFOCUS, a default parameter in ASP.NET 2.0, is vulnerable to reflexif cross site scripting (CSS).

One suggested solution was to apply the patch MS06-056/KB922770 on the server. (Downloadable from http://www.microsoft.com/technet/security/Bulletin/MS06-056.mspx.)

Unfortunately, the patch is not getting installed. The below link from microsoft suggested re-installing the framework:

I did, but no luck - the patch would not install!

Any solutions? My main problem is to get rid of CSS - please suggest.

> .. a default parameter in ASP.NET 2.0,
do you use that parameter? if not simply disable the corresponding script.

then I see following possibilities:
1) wait 'til you get an installable patch
2) fix the code
3) write a wrapper script which checks its input for XSS and forwards to the vulnerable script if the input matches your rules
