In PHOENIX CONTACTs TC ROUTER and TC CLOUD CLIENT in versions prior to 2.07.2 as well as CLOUD CLIENT 1101T-TX/TX prior to 2.06.10 an authenticated remote attacker with admin privileges could upload a crafted XML file which causes a denial-of-service.

Weakness

The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.
