Xoops 2.5.7.2
Vulnerability Type:
===================
Weak Crypto
Vulnerability Details:
=====================
Xoops 2.5.7.2 uses weak one way hash crypto MD5 along with unsalted
passwords stored in the database.
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 Xoops code in 'register.php' line 192 we find following...
$newuser->setVar('pass', md5($pass), true);
