Synopsis

Joomla! 2.5.x < 3.9.17 Multiple Vulnerabilities

Description

According to its self-reported version, the instance of Joomla! running on the remote web server is 2.5.x prior to 3.9.17. It is, therefore, affected by multiple vulnerabilities :

- Incorrect ACL checks in the access level section of com_users allow the unauthorized deletion of usergroups. (CVE-2020-11889)

- Improper input validations in the usergroup table class could lead to a broken ACL configuration. (CVE-2020-11890)

- Incorrect ACL checks in the access level section of com_users allow the unauthorized editing of usergroups. (CVE-2020-11891)

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 3.9.17 or latest.
