There is a vulnerability in IIS4.0 which allows for a user to view the asp source code of a given page on the server. It works like this:<br><br>Suppose you have an asp page at:<br><br><A HREF=" TARGET="_new"> you insert the domain name and file name into the following formula:<br><br><font color=red>DOMAINNAME</font>/null.htw?CiWebHitsFile=/<font color=red>FILEPATH</font>%20&CiRestriction=none&CiHiliteType=Full<br><br>like this,<br><br><A HREF=" TARGET="_new"> type this into your browser, in some cases you will see the server source code for the asp page. It doesn't always work but I've looked at the source code for a number of large sites this way. I know Microsoft has a patch for this but I can't find it. Has any one dealt with this problem and worked with the patch?<br>Any comments or information greatly appreciated (as well as any other security holes anyone might know about regarding asp and IIS4.0)<br><br><br> <p>--Will Duty<br><a href=mailto:wduty@radicalfringe.com>wduty@radicalfringe.com</a><br><a href= > </a><br>
