CVE-2015-1108: Apple iPhone OS

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

The Lock Screen component in Apple iOS before 8.3 does not properly enforce the limit on incorrect passcode-authentication attempts, which makes it easier for physically proximate attackers to obtain access by making many passcode guesses.

Affected products

• Apple iPhone OS: up to and including 8.2
