9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2023-23302
Critical (9.8) in garmin connect-iq. EPSS 1.3% chance of exploitation in the next 30 days.
The `Toybox.GenericChannel.setDeviceConfig` API method in CIQ API version 1.2.0 through 4.1.7 does not validate its parameter, which can result in buffer overflows when copying various attributes. A malicious application could call the API method with specially crafted object and hijack the execution of the device's firmware.
