Critical account creation flaws patched in popular Joomla CMS

Developers urge users to update to Joomla 3.6.4 as soon as possible

The Joomla developers are warning website administrators to apply an update for the popular content management system that fixes two critical vulnerabilities.

The flaws are serious enough that the Joomla project released a prenotification about the planned update on Friday, urging everyone to be prepared to install it as soon as possible. This suggests that attacks targeting these vulnerabilities are expected to follow shortly.

Joomla 3.6.4, released Tuesday, fixes a high-priority flaw in the account creation component that could be exploited to create accounts on a Joomla-based website even if user registration has been disabled on it.

A second vulnerability patched in this update is described as a privilege escalation issue and allows users to register on a Joomla website with elevated privileges.

It's easy to see how these two vulnerabilities could be used by hackers to bypass important security controls and gain unauthorized access to websites.

A third bug was fixed in the encryption scheme used by the Joomla two-factor authentication system, although this is not marked as a vulnerability.

Joomla is the second most popular platform for building websites after WordPress, making it a favorite target for hackers. Last year, attackers started exploiting a critical Joomla vulnerability less than four hours after a patch was released for it.

While WordPress is used by many users to build personal blogs, Joomla is used primarily by companies to create complex public-facing and internal websites.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
