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.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.4, with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), limited integrity, and limited availability for affected systems. Impacting 2 products from siemens, from siemens organizations running these solutions should prioritize assessment and patching.
First disclosed in 2017, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For siemens's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
