Status: ModifiedHigh (8.8)—

An issue was discovered in 3xLogic Infinias Access Control through 6.7.10708.0, affecting physical security. Users with login credentials assigned to a specific zone can send modified HTTP GET and POST requests, allowing them to view user data such as personal information and Prox card credentials. Also, an authorized user of one zone can send API requests to unlock electronic locks associated with zones they are unauthorized to have access to. They can also create new user logins for zones they were not authorized to access, including the root zone of the software.
