CVE-2021-20832

Measurement-result disclosure via post-test device pairing

Published Oct 13, 2021 · Updated Aug 3, 2024

Information disclosure in InBody App before iOS 2.3.30 and Android 2.2.90(510) allows physically proximate attackers to read results. Older app versions accept a completed InBody Dial measurement that was started directly on the device and transfer it to an app connected immediately afterward. Exploitation requires a victim to complete a test and a nearby attacker to pair an app at that time; the disclosed data is the victim's body-composition result.
