3.7 (Low) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:L
Summary
XML External Entity in Dashboard Widget
Details

Problem

It has been discovered that RSS widgets are susceptible to XML external entity processing. This vulnerability is reasonable, but is theoretical - it was not possible to actually reproduce the vulnerability with current PHP versions of supported and maintained system distributions.

At least with libxml2 version 2.9, the processing of XML external entities is disabled per default - and cannot be exploited. Besides that, a valid backend user account is needed.

Solution

Update to TYPO3 version 10.4.10 that fixes the problem described.
