Descriptions

In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.17 and greater than or equal to 10.0.0 and less than 10.4.2, calling unserialize() on malicious user-submitted content can lead to modification of dynamically-determined object attributes and result in triggering deletion of an arbitrary directory in the file system, if it is writable for the web server. It can also trigger message submission via email using the identity of the web site (mail relay). Another insecure deserialization vulnerability is required to actually exploit mentioned aspects. This has been fixed in 9.5.17 and 10.4.2.

En TYPO3 CMS versiones mayores o iguales a 9.0.0 y menores a 9.5.17 y versiones mayores o iguales a 10.0.0 y versiones menores a 10.4.2, al llamar la función unserialize() sobre un contenido malicioso enviado por el usuario puede conllevar a una modificación de determinados atributos de objeto y resultar en la eliminación de un directorio arbitrario en el sistema de archivos, si es escribible para el servidor web. También puede activar el envío de mensajes por medio de correo electrónico utilizando la identidad del sitio web (retransmisión de correo). Es requerida otra vulnerabilidad de deserialización no segura para explotar realmente los aspectos mencionados. Esto ha sido corregido en las versiones 9.5.17 y 10.4.2.
