The safe_eval function in trytond in Tryton before 2.4.15, 2.6.x before 2.6.14, 2.8.x before 2.8.11, 3.0.x before 3.0.7, and 3.2.x before 3.2.3 allows remote authenticated users to execute arbitrary commands via shell metacharacters in (1) the collection.domain in the webdav module or (2) the formula field in the price_list module.
The client in Tryton 5.x before 5.0.1 tries to make a connection to the bus in cleartext instead of encrypted under certain circumstances in bus.py and jsonrpc.py. This connection attempt fails, but it contains in the header the current session of the user. This session could then be stolen by a man-in-the-middle.
file_open in Tryton allows remote authenticated users with certain permissions to read arbitrary files via a "same root name but with a suffix" attack.
