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); References: http://xoops.org/modules/news/article.php?storyid=6757 Disclosure Date: =================================== Jan 29, 2016: Vendor Notification Vendor confirms and patches Xoops March 17, 2016 : Public Disclosure =================================== [+] Disclaimer Permission is hereby granted for the redistribution of this advisory, provided that it is not altered except by reformatting it, and that due credit is given.
