CVE-2018-19981
An attacker can use these credentials to create authenticated and/or authorized requests.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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).
