CVE-2018-19981: Amazon Aws Software Development Kit

High severity, CVSS 7.2. EPSS: 1.8% chance of exploitation in the next 30 days.

Amazon AWS SDK <=2.8.5 for Android uses Android SharedPreferences to store plain text AWS STS Temporary Credentials retrieved by AWS Cognito Identity Service. An attacker can use these credentials to create authenticated and/or authorized requests. Note that the attacker must have "root" privilege access to the Android filesystem in order to exploit this vulnerability (i.e. the device has been compromised, such as disabling or bypassing Android's fundamental security mechanisms).

Affected products

• Amazon Aws Software Development Kit: up to and including 2.8.5
