TYPO3 is an open source PHP based web content management system. In versions prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 TYPO3 is vulnerable to Improper Authentication. Restricting frontend login to specific users, organized in different storage folders (partitions), can be bypassed. A potential attacker might use this ambiguity in usernames to get access to a different account - however, credentials must be known to the adversary. This issue is patched in versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the d9e154c9-7de9-11ed-adca-080027d3a315 advisory.

  - HTML sanitizer is written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags,     attributes and values. In versions prior to 1.5.0 or 2.1.1, malicious markup used in a sequence with     special HTML CDATA sections cannot be filtered and sanitized due to a parsing issue in the upstream     package masterminds/html5. This allows bypassing the cross-site scripting mechanism of typo3/html-     sanitizer. The upstream package masterminds/html5 provides HTML raw text elements (`script`, `style`,     `noframes`, `noembed` and `iframe`) as DOMText nodes, which were not processed and sanitized further. None     of the mentioned elements were defined in the default builder configuration, that's why only custom     behaviors, using one of those tag names, were vulnerable to cross-site scripting. This issue has been     fixed in versions 1.5.0 and 2.1.1. (CVE-2022-23499)

  - TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33,     11.5.20, and 12.1.1, requesting invalid or non-existing resources via HTTP triggers the page error     handler, which again could retrieve content to be shown as an error message from another page. This leads     to a scenario in which the application is calling itself recursively - amplifying the impact of the     initial attack until the limits of the web server are exceeded. This vulnerability is very similar, but     not identical, to the one described in CVE-2021-21359. This issue is patched in versions 9.5.38 ELTS,     10.4.33, 11.5.20 or 12.1.1. (CVE-2022-23500)

  - TYPO3 is an open source PHP based web content management system. In versions prior to 8.7.49, 9.5.38,     10.4.33, 11.5.20, and 12.1.1 TYPO3 is vulnerable to Improper Authentication. Restricting frontend login to     specific users, organized in different storage folders (partitions), can be bypassed. A potential attacker     might use this ambiguity in usernames to get access to a different account - however, credentials must be     known to the adversary. This issue is patched in versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20,     12.1.1. (CVE-2022-23501)

  - TYPO3 is an open source PHP based web content management system. In versions prior to 10.4.33, 11.5.20,     and 12.1.1, When users reset their password using the corresponding password recovery functionality,     existing sessions for that particular user account were not revoked. This applied to both frontend user     sessions and backend user sessions. This issue is patched in versions 10.4.33, 11.5.20, 12.1.1.
    (CVE-2022-23502)

  - TYPO3 is an open source PHP based web content management system. Versions prior to 8.7.49, 9.5.38,     10.4.33, 11.5.20, and 12.1.1 are vulnerable to Code Injection. Due to the lack of separating user-     submitted data from the internal configuration in the Form Designer backend module, it is possible to     inject code instructions to be processed and executed via TypoScript as PHP code. The existence of     individual TypoScript instructions for a particular form item and a valid backend user account with access     to the form module are needed to exploit this vulnerability. This issue is patched in versions 8.7.49     ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1. (CVE-2022-23503)

  - TYPO3 is an open source PHP based web content management system. Versions prior to 9.5.38, 10.4.33,     11.5.20, and 12.1.1 are subject to Sensitive Information Disclosure. Due to the lack of handling user-     submitted YAML placeholder expressions in the site configuration backend module, attackers could expose     sensitive internal information, such as system configuration or HTTP request messages of other website     visitors. A valid backend user account having administrator privileges is needed to exploit this     vulnerability. This issue has been patched in versions 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.
    (CVE-2022-23504)

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

The version of TYPO3 installed on the remote host is prior to 8.0.0 < 8.7.49 ELTS / 9.0.0 < 9.5.38 ELTS / 10.0.0 < 10.4.33 / 11.0.0 < 11.5.20 / 12.0.0 < 12.1.1. It is, therefore, affected by a vulnerability as referenced in the TYPO3-CORE-SA-2022-013 advisory.
