Description#
DbGate before 7.3.3 contains a missing authorization vulnerability that allows connection-restricted authenticated users to bypass LOGIN_PERMISSIONS because test() and save() never call testConnectionPermission. Attackers can submit arbitrary connection definitions to POST /connections/test to probe internal database hosts, or to /connections/save to overwrite stored connections.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact none. Attack vector: network.
