A vulnerability has been identified in SCALANCE LPE9403 (All versions < V2.1). The `i2c` mutex file is created with the permissions bits of `-rw-rw-rw-`. This file is used as a mutex for multiple applications interacting with i2c. This could allow an authenticated attacker with access to the SSH interface on the affected device to interfere with the integrity of the mutex and the data it protects.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 3.3, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited integrity, for affected systems. Impacting 2 products from siemens, from siemens 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 siemens'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.
