Improperly Controlled Modification of Dynamically-Determined Object Attributes in TYPO3 CMS

State: Published
Severity: 8.7 High
Published: May 13, 2020
Updated: Aug 4, 2024
Reserved: Mar 30, 2020

Description

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.
