    Well i have no more clue of hotfixes but there seems to be other
    problems with %3F and jsp. And am sorry if this is old.
    
    I just tryed this on my IIS5 sp2 with most hotfixes and Resin 2.0.1
    installed.
    
    http://server/default.asp%3F.jsp
    
    And it just droped me the asp source. Got similar result with alliere
    jrun.
    
    I think i seen a post here somewhere about %3F.jsp gets you a filelist
    if you try something like http://server/%3F.jsp to.
    
    A fix for it seems to be to set the rights on the site to Script only.
    
    Regards,

    *I have no clue if this is a new bug or not due to my 
    
    lack of hotfixes, but here it goes!*
    
    
    
    Hello fellow vuln-dev'ers,
    
    Here is a srange bug ive found on my test server:
    
    
    
    Microsoft Windows 2000 [Version 5.00.2195]  
    
    (service pack 2)
    
    
    
    Making the following request:
    
    
    
    http://bender/global.asa%3f.htr
    
    
    
    Adding a %3f.htr at the end seems to yield its source 
    
    code.  Because this is a default install, all that it 
    
    contains is the following:
    
    
    
    <OBJECT RUNAT=Server SCOPE=Session 
    
    ID=MyInfo PROGID="MSWC.MyInfo">
    
    </OBJECT>
    
       
    
    Ive tried appending  %3f.htr to iisstart.asp (another 
    
    default file), but that does not reveal a thing.  
    
    Renaming iisstart.asp to iisstart.asa and trying to 
    
    view its source does not work then either.  I cant find 
    
    any logic behind this. Please give this a shot, play 
    
    with this, and send in your results/thoughts!
    
    
    
    Best Regards,
