Some Huawei smart phones with the versions before Berlin-L21HNC185B381; the versions before Prague-AL00AC00B223; the versions before Prague-AL00BC00B223; the versions before Prague-AL00CC00B223; the versions before Prague-L31C432B208; the versions before Prague-TL00AC01B223; the versions before Prague-TL00AC01B223 have an information exposure vulnerability. When the user's smart phone connects to the malicious device for charging, an unauthenticated attacker may activate some specific function by sending some specially crafted messages. Due to insufficient input validation of the messages, successful exploit may cause information exposure.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.6, with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 14 products from huawei, from huawei, from huawei and 11 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, 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 huawei'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.
