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.

Joomla! Core is prone to a session fixation vulnerability. An attacker may leverage this issue to hijack an arbitrary session and gain access to sensitive information, which may help in launching further attacks. Joomla! Core versions 1.5.x ranging from 1.5.0 and up to and including 1.5.15 are vulnerable.
