Introduction
Joomla is one of the most popular open-source content management systems. It is especially a common target for attackers due to its popularity and the wide variety of extensions that are available to us. Therefore, we would recommend you to use some Joomla security scans to test your site. Besides, the scans are also useful to detect security issues, configuration errors, and poor reputation links. Thus, by using them, you can get to work mitigating the vulnerabilities.
Vulnerability
The vulnerability allows hackers to hack Joomla websites through the Media Manager. To exploit the vulnerability, the attacker has to find a Joomla site that allows access to the media manager to its users. Then, s/he will register an account and use the vulnerability. They will use it to upload a malicious shell script to this site through the Media Manager. After that, the attacker can do pretty much anything like edit your files, access your database, delete information, and others.
