Joomla SQL Injection Vulnerability Exploit Results in Full Administrative Access
Trustwave SpiderLabs researcher Asaf Orpani has discovered an SQL injection vulnerability in versions 3.2 through 3.4.4 of Joomla, a popular open-source Content Management System (CMS). Combining that vulnerability with other security weaknesses, our Trustwave SpiderLabs researchers are able to gain full administrative access to any vulnerable Joomla site.
Joomla had a 6.6 percent share of the market for website CMSs as of October 20, 2015 according to W3Techs—second only to WordPress. Internet services company BuiltWith estimates that as many as 2.8 million websites worldwide use Joomla.
The vulnerability can be exploited in Joomla versions 3.2 (released in November 2013) through version 3.4.4.
Because the vulnerability is found in a core module that doesn’t require any extensions, all websites that use Joomla versions 3.2 and above are vulnerable.
