Descriptions

TYPO3 is an open source PHP based web content management system. In TYPO3 from version 10.4.0, and before version 10.4.10, 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. Update to TYPO3 version 10.4.10 to fix the problem described.

TYPO3 es un sistema de administración de contenido web de código abierto basado en PHP. En TYPO3 desde la versión 10.4.0, y anterior a versión 10.4.10, los widgets RSS son susceptibles al procesamiento de entidades externas XML. Esta vulnerabilidad es razonable, pero es teórica: no fue posible reproducir la vulnerabilidad con las versiones actuales de PHP de las distribuciones del sistema compatibles y mantenidas. Al menos con libxml2 versión 2.9, el procesamiento de entidades externas XML está deshabilitado por defecto y no puede ser explotada. Además de eso, se necesita una cuenta de usuario de backend válida. Actualice a TYPO3 versión 10.4.10 para corregir el problema descrito
