According to its self-reported version, the instance of Joomla! running on the remote web server is 4.2.x prior to 4.3.2. It is, therefore, affected by multiple vulnerabilities.
An issue was discovered in Joomla! 4.2.0 through 4.3.1. Lack of input validation caused an open redirect and XSS issue within the new mfa selection screen. (CVE-2023-23754)
An issue was discovered in Joomla! 4.2.0 through 4.3.1. The lack of rate limiting allowed brute force attacks against MFA methods. (CVE-2023-23755)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
