P30, P30 Pro, Mate 20 smartphones with software of versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1), versions earlier than VOGUE-AL00A 9.1.0.193(C00E190R2P1), versions earlier than Hima-AL00B 9.1.0.135(C00E133R2P1) and HiSuite with versions earlier than HiSuite 9.1.0.305 have a version downgrade vulnerability. The device and HiSuite software do not validate the upgrade package sufficiently, so that the system of smartphone can be downgraded to an older version.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.5, requiring local system access to exploit with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts integrity (unauthorized modifications), for affected systems. Impacting 8 products from huawei, from huawei, from huawei and 5 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2019, 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.
