CVE-2020-28952
An issue was discovered on Athom Homey and Homey Pro devices before 5.0.0.
Impact
An issue was discovered on Athom Homey and Homey Pro devices before 5.0.0. ZigBee hub devices should generate a unique Standard Network Key that is then exchanged with all enrolled devices so that all inter-device communication is encrypted. However, the cited Athom products use another widely known key that is designed for testing purposes: "01030507090b0d0f00020406080a0c0d" (the decimal equivalent of 1 3 5 7 9 11 13 15 0 2 4 6 8 10 12 13), which is human generated and static across all issued devices.
Affected products
| Vendor | Product | Affected versions |
|---|---|---|
| Homey | Homey Firmware | before 5.0.0 |
| Homey | Homey Pro Firmware | before 5.0.0 |
