Post-authentication remote command injection vulnerability in Western Digital My Cloud OS 5 devices that could allow an attacker to execute code in the context of the root user on vulnerable CGI files. This vulnerability can only be exploited over the network and the attacker must already have admin/root privileges to carry out the exploit. An authentication bypass is required for this exploit, thereby making it more complex. The attack may not require user interaction. Since an attacker must already be authenticated, the confidentiality impact is low while the integrity and availability impact is high. This issue affects My Cloud OS 5 devices: before 5.26.300.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.2, indicating it can be exploited remotely over the network but requires specific conditions to be met without requiring user interaction . The vulnerability impacts limited data confidentiality, integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 11 products from westerndigital, from westerndigital, from westerndigital and 8 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.
