Vulnerability Type:  
===================  
Weak Crypto  
  
  
  
Vulnerability Details:  
=====================  
  
Coppermine stores users passwords in using weak MD5 hash function without  
any salt.  
  
Using weak cryptographic one-way hash functions like MD5 without using salt  
for storing user passwords allows attackers  
that gain access to this data ability to conduct password cracking attacks  
using pre-computed dictionaries, e.g. rainbow tables.  
if their local machine is compromised and attackers gain access to the MD5  
hashed passwords.  
  
e.g.  
  
e99a18c428cb38d5f260853678922e03 MD5 : abc123  
  
  
In register.php line 591 we find following md5 one way hash function  
applied to users password with no salt whatsoever, then stored in DB.  
  
$encpassword = md5($password);  
  
  
  
$user_language = $CONFIG['lang'];  
  
  
$sql = "INSERT INTO {$CONFIG['TABLE_USERS']} (user_regdate, user_active,  
user_actkey, user_name, user_password, user_email, user_profile1,  
user_profile2, user_profile3, user_profile4, user_profile5, user_profile6,  
user_language) VALUES (NOW(), '$active', '$act_key', '$user_name',  
'$encpassword', '$email', '$profile1', '$profile2', '$profile3',  
'$profile4', '$profile5', '$profile6', '$user_language')";  
$result = cpg_db_query($sql);
