Alfresco Activiti Process Variable Serialization System SerializableType.java createObjectInputStream deserialization

A flaw has been found in Alfresco Activiti up to 7.19/8.8.0. Affected by this issue is the function deserialize/createObjectInputStream of the file activiti-core/activiti-engine/src/main/java/org/activiti/engine/impl/variable/SerializableType.java of the component Process Variable Serialization System. This manipulation causes deserialization. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
