Synopsis

Joomla! 2.5.x < 3.9.28 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 3.9.28. It is, therefore, affected by multiple vulnerabilities.

 - Inadequate escaping in the Rules field of the JForm API leads to a Cross-Site Scripting (XSS) vulnerability. (CVE-2021-26035)

 - Missing validation of input could lead to a broken usergroups table. (CVE-2021-26036)

 - Various CMS functions did not properly termine existing user sessions when a user's password was changed or the user was blocked. (CVE-2021-26037)

 - Install action in com_installer lack the required hardcoded ACL checks for superusers, leading to various potential attack vectors. (CVE-2021-26038)

 - Inadequate escaping in the imagelist view of com_media leads to a Cross-Site Scripting (XSS) vulnerability. (CVE-2021-26039)

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 3.9.28 or latest.
