A vulnerability was discovered in Siemens SIMATIC WinCC Sm@rtClient for Android (All versions before V1.0.2.2) and SIMATIC WinCC Sm@rtClient for Android Lite (All versions before V1.0.2.2). An attacker with physical access to an unlocked mobile device, that has the affected app running, could bypass the app's authentication mechanism under certain conditions.

The Siemens SIMATIC WinCC Sm@rtClient and Sm@rtClient Lite applications before 01.00.01.00 for Android do not properly store passwords, which allows physically proximate attackers to obtain sensitive information via unspecified vectors.
