SCA: security update for typo3/cms, typo3/cms-core (GHSA-m2jh-fxw4-gphm)

medium Tenable Self-Hosted Container Security Plugin ID 416657

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been
 discovered that TYPO3 CMS is susceptible to host spoofing due to improper validation of the HTTP Host
 header. TYPO3 uses the HTTP Host header, for example, to generate absolute URLs during the frontend
 rendering process. Since the host header itself is provided by the client, it can be forged to any value,
 even in a name-based virtual hosts environment. This vulnerability is the same as described in TYPO3-CORE-
 SA-2014-001 (CVE-2014-3941). A regression, introduced during TYPO3 v11 development, led to this situation.
 The already existing setting $GLOBALS['TYPO3_CONF_VARS']['SYS']['trustedHostsPattern'] (used as an
 effective mitigation strategy in previous TYPO3 versions) was not evaluated anymore, and reintroduced the
 vulnerability. (CVE-2021-41114)
