# Software description:
# The employee monitoring software developed by Cyclope-Series is specially designed to inform 
# and equip management with statistics relating to the productivity of staff within their organization. 
  
# Vulnerability:
# Due to insecure file Permissions, a low privileged could potentially 
# delete, modify or replace many of the key executable files used, and needed
# by the software.
 
# Although I haven't checked older versions, I do recall seeing the same file
# permissions being set. Making this software extremely prone to lots of fun stuff.
 
''' File Information '''
A few files with odd-ball permission. Keep in mind all files are like this.
All files in c:\xampplite, as well as  in Program Files.
The "CyclopeClient.exe" is is what is pushed to workstation in order to monitor
employees. As we can see, this file's permission is set to "Everybody". So is the
uninstaller executable.
 
So gain access to the system, and as a low privileged user one can
easily replace httpd.exe or mysqld.exe, with an evil EXE file.
Next time that file is executed, you'll get your shell as SYSTEM.
Although they'll be out of a service...bummer
