-= Mirabilis ICQ WebFront Plug-in Denial of Service =-
Release date: Saturday, April 28, 2001
Introduction:
WebFront is a plugin for Mirabilis' ICQ messaging program which
allows a user to setup a web page through ICQ.
ICQ WebFront is available for ICQ from vendor Mirabilis'
website: http://www.icq.com
Problem:
The web server on which this plugin relies is susceptible to a DoS
attack through a malformed GET request. If this request contains
86 or more %'s or combinations of %'s with other characters (for
example ascii encoded dots or backslashes) the ICQ program will
begin consuming 100% cpu and will become unresponsive.
A restart of the program is required to regain full functionality.
(..)
Solution:
This problem has been brought to the vendors attention, however no
fixes appear to be forthcoming at this time, we were only able to get a
"your message has been forwarded to the appropiate address" response.
This was tested against ICQ2000b Build 3278 running on MS Win2k.
