Description

The Mira cloud API accepts the firmware version reported by the companion app as authoritative for a given device, without independently attesting the version from the device itself. An authenticated attacker could submit arbitrary firmware version strings for their own device, allowing them to evade vendor-side vulnerable-fleet analytics, suppress security update prompts to the user, and misrepresent patch-adoption metrics.

Affected products

Quanovate Tech Inc. (operating as Mira / Mira Care) Mira Android App: 4.5.15.4
Quanovate Tech Inc. (operating as Mira / Mira Care) Mira Firmware: 1.7.1.47
