Synopsis

The remote webserver is affected by a XSS vulnerability

Description

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-2022-017 advisory.

 - Due to a parsing issue in the upstream package masterminds/html5, malicious markup used in a sequence with special HTML CDATA sections cannot be filtered and sanitized. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer. Besides that, 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. (CVE-2022-23499)

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

Solution

Upgrade to TYPO3 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1 or later.
