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).

Description
A cleartext-credential issue was discovered in the Amazon AWS SDK 2.8.5 for Android. This SDK uses Android SharedPreferences to store AWS STS Temporary Credentials retrieved by AWS Cognito Identity Provider. If a Mobile Application (MA) uses AWS Cognito in the authentication or authorization process, the AWS SDK will store these credentials in cleartext inside the "com.amazonaws.android.auth" SharedPref. An attacker can use these credentials to create and sign valid AWS Signature v4 requests, and perform authenticated and authorized application actions at the user's expense. Note that the attacker must have root access to the Android filesystem (i.e., the device must already be compromised, such as by malware).
