Joomla! 2.5.0 < 3.9.3 Multiple Vulnerabilities

critical Nessus Plugin ID 122346

Synopsis

The remote web server contains a PHP application that is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Joomla! installation running on the remote web server is prior to 3.9.3. It is, therefore, affected by multiple vulnerabilities:

- An object injection vulnerability exists in Joomla! prior to 3.9.3 due to the absence of a protection mechanism to prevent the use of the phar:// handler for non .phar files. An unauthenticated, remote attacker can exploit this to include arbitrary files (CVE-2019-7743).

- A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session (CVE-2019-7740, CVE-2019-7741, CVE-2019-7744).

- An issue exists in Joomla! prior to 3.9.3. The 'No Filtering' textfilter overrides child settings in the Global Configuration.
This is intended behavior. However, it might be unexpected for the user because the configuration dialog lacks an additional message to explain this (CVE-2019-7739).

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Joomla! version 3.9.3 or later.
