QID 154098

Joomla! Core is prone to a security bypass vulnerability. Exploiting this issue may allow attackers to perform otherwise restricted actions and subsequently retrieve password reset tokens from the database through an already existing SQL injection vector. Joomla! Core versions 1.5.x ranging from 1.5.0 and up to and including 1.5.15 are vulnerable.

When a user requests a password reset, the reset tokens were stored in plain text in the database. While this is not a vulnerability in itself, it allows user accounts to be compromised if there is an extension on the site with an existing SQL injection vulnerability.
