Synopsis

A PHP application running on the remote web server is affected by multiple vulnerabilities.

According to its self-reported version, the instance of Joomla! running on the remote web server is 2.5.x prior to 3.9.20. It is, therefore, affected by multiple vulnerabilities.

- A missing token check in the ajax_install endpoint com_installer causes a CSRF vulnerability. (20200701)

- Missing validation checks at the usergroups table object can result into an broken site configuration.
(CVE-2020-15699)

(CVE-2020-15695)

- Internal read-only fields in the User table class could be modified by users. (CVE-2020-15697)

- Lack of input filtering and escaping allows XSS attacks in mod_random_image (CVE-2020-15696)

- Inadequate filtering in the system information screen could expose redis or proxy credentials (CVE-2020-15698)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
