Synopsis

Joomla! 3.6.x < 3.6.4 Multiple Vulnerabilities

Description

According to its self-reported version number, the detected Joomla! application is affected by multiple vulnerabilities :

 - A privilege escalation vulnerability exists in the Joomla! core user registration component due to improper processing of unfiltered data. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to register an account on a Joomla! site with elevated privileges. (CVE-2016-8869)

 - A security bypass vulnerability exists in the Joomla! core user registration component due to insufficient checks on whether user registration is disabled. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to register an account on a Joomla! site even when account registration has been disabled. (CVE-2016-8870)

 - A flaw exists in the Joomla! core user modification component due to the improper processing of unfiltered data. An attacker can exploit this to modify the username, password, and user group for existing user accounts. (CVE-2016-9081)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Joomla! version 3.6.4 or latest.
