Technical Analysis
There are at least two ways to achieve RCE.
Vector n°1
It leaks the MySQL credentials, in default and most common configurations MySQL will be exposed only on 127.0.0.1
which make the attack ineffective. But if the database is exposed publicly, the attacker can change the Joomla! Super User’s password. The attacker logs in administrative web interface and modify a template to include a webshell or install a malicious plugin.
Vector n°2
It leaks the Joomla user database (usernames, emails, assigned group). The attacker can target a Super user and try bruteforce or credentials stuffing, then follows previously showcased paths to code execution.
