CVE-2019-1595

CVE-2019-1595 describes a denial-of-service vulnerability in the Fibre Channel over Ethernet (FCoE) protocol implementation within Cisco NX-OS Software, affecting Nexus 5600 and 6000 series switches. This flaw stems from an incorrect internal interface index allocation, allowing an unauthenticated, adjacent attacker to craft a malicious FCoE packet. Successful exploitation could lead to a packet loop and high throughput on affected interfaces, causing a denial of service. While rated Medium severity (CVSS 6.5), there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
