A buffer overflow vulnerability was discovered on firmware version validation that could lead to an unauthenticated remote code execution in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi devices. An attacker would require exploitation of another vulnerability to raise their privileges in order to exploit this buffer overflow vulnerability. This issue affects My Cloud Home and My Cloud Home Duo: before 9.4.0-191; ibi: before 9.4.0-191.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 1.9, requiring local system access to exploit but requires specific conditions to be met without requiring user interaction . The vulnerability impacts limited data confidentiality, for affected systems. Impacting 6 products from westerndigital, from westerndigital, from westerndigital and 3 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

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 westerndigital'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.
