The Mobile and Remote Access (MRA) services implementation in Cisco Unified Communications Manager mishandles edge-device identity validation, which allows remote attackers to bypass intended call-reception and call-setup restrictions by spoofing a user, aka Bug ID CSCuu97283.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
