Synopsis

The remote webserver is affected by a XSS vulnerability

Description

The version of TYPO3 installed on the remote host is prior to 8.7.42 < 8.7.53 ELTS / 9.5.29 < 9.5.42 ELTS / 10.4.19 < 10.4.39 ELTS / 11.3.2 < 11.5.30 / 12.0.0 < 12.4.4. It is, therefore, affected by a vulnerability as referenced in the TYPO3-CORE-SA-2023-002 advisory.

 - Due to an encoding issue in the serialization layer, malicious markup nested in a noscript element was not encoded correctly. noscript is disabled in the default configuration, but might have been enabled in custom scenarios. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer.
 (CVE-2023-38500)

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 8.7.53 ELTS, 9.5.42 ELTS, 10.4.39 ELTS, 11.5.30, 12.4.4 or later.
