CVE-2018-0301: A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attack...

A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to craft a packet to the management interface on an affected system, causing a buffer overflow. The vulnerability is due to incorrect input validation in the authentication module of the NX-API subsystem. An attacker could exploit this vulnerability by sending a crafted HTTP or HTTPS packet to the management interface of an affected system with the NX-API feature enabled. An exploit could allow the attacker to execute arbitrary code as root. Note: NX-API is disabled by default. This vulnerability affects: MDS 9000 Series Multilayer Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules. Cisco Bug IDs: CSCvd45804, CSCve02322, CSCve02412.

Security readout for executives and security teams

CVE-2018-0301 is a Cisco NX-OS NX-API flaw that can let an unauthenticated remote attacker run code as root on affected devices. NX-API is disabled by default, so urgency depends on whether it is enabled and reachable on the management interface. Exposure is most likely on Cisco MDS 9000 and Nexus platforms listed by Cisco where NX-API is enabled and the management interface is reachable from untrusted networks. The bundle does not provide affected NX-OS version ranges. Treat as urgent for any affected Cisco switch with NX-API enabled. The business risk is management-plane takeover with root-level execution, but devices without NX-API enabled have materially lower exposure based on the source bundle. Mitigation focus: Check Cisco advisory cisco-sa-20180620-nxos-bo for fixed NX-OS releases and upgrade guidance.; Disable NX-API on devices where it is not operationally required.; Restrict management interfaces to trusted administrative networks only..
