The Fibre Channel over Ethernet (FCoE) feature in IBM System Networking and Blade Network Technology (BNT) switches running IBM Networking Operating System (aka NOS, formerly BLADE Operating System) floods data frames with unknown MAC addresses out on all interfaces on the same VLAN, which might allow remote attackers to obtain sensitive information in opportunistic circumstances by eavesdropping on the broadcast domain. IBM X-Force ID: 83166.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.3, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 12 products from ibm, from ibm, from ibm and 9 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, 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 ibm'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.
