Remote/Local DoS on I.E. 4.x
I looked if this was a known vulnerability, but I could not find any info on
it. Neither could my phriends & phoes in news://alt.hack.nl If this is a
known vulnerability, then I give a bucket of credit to the original
It is possible to crash Internet Explorer 4.x by simply feeding it this
link: ' ftp://: '
All open Internet Explorer/Explorer windows will close down and it will
reset your "Active Desktop" (damn sh4m3). Opening ftp://: from applications
like RealPlayer or Windows Media Player will result in the DoS on them
Our friend, Dr. Watson, had this to say:
"An appication error has occured and an application error log is being
explorer.exe [or Internet Explorer, depends on where you open it]
Exception: access violation (0xc0000005), Address: 0x7020dd84"
And Event Viewer told me:
"The shell stopped unexpectedly and explorer.exe was restarted."
A funny side-effect is that if you minimize your ICQ (probably works on some
other applications aswell) after the crash it will completely dissapear. Its
not on your screen anymore and you won't find it iin Task
Manager/Applications either, yet its still active! It showed up in Task
Manager/Processes. You can get it back by simply restarting ICQ, you'll get
a message that "ICQ is already running" and then it'll show up again.
Okay, the s00p3r 3xpl0!t:
Or trigger it remote by using the infamous ICQ Greeting-card vulnerability.
Put the following line in the body of your ICQ Greeting-card:
<meta http-equiv="REFRESH" content="3; URL=ftp://:">
Yes, I know. IE 4 is old news, but its still widely used. I'm taking my time
to upgrade to SP6/NT5, and I know I shouldn't. Future exploits will be
comming from a more recent platform.
