In Lenovo Connect2 versions earlier than 4.2.5.4885 for Windows and 4.2.5.3071 for Android, when an ad-hoc connection is made between two systems for the purpose of sharing files, the password for this ad-hoc connection will be stored in a user-readable location. An attacker with read access to the user's contents could connect to the Connect2 hotspot and see the contents of files while they are being transferred between the two systems.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.8, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 3 products from lenovo, from microsoft, from google 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 lenovo'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.
