Authentication bypass vulnerability in Fujitsu network devices Si-R series and SR-M series allows a network-adjacent unauthenticated attacker to obtain, change, and/or reset configuration settings of the affected products. Affected products and versions are as follows: Si-R 30B all versions, Si-R 130B all versions, Si-R 90brin all versions, Si-R570B all versions, Si-R370B all versions, Si-R220D all versions, Si-R G100 V02.54 and earlier, Si-R G200 V02.54 and earlier, Si-R G100B V04.12 and earlier, Si-R G110B V04.12 and earlier, Si-R G200B V04.12 and earlier, Si-R G210 V20.52 and earlier, Si-R G211 V20.52 and earlier, Si-R G120 V20.52 and earlier, Si-R G121 V20.52 and earlier, and SR-M 50AP1 all versions.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.8, indicating it requires adjacent network access with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 32 products from fujitsu, from fujitsu, from fujitsu and 29 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 fujitsu'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.
