The vulnerability is due to improper signature verification during the installation of an Open Virtual Appliance (OVA) image. An authenticated, local attacker could exploit this vulnerability and load a malicious, unsigned OVA image on an affected device. A successful exploit could allow an attacker to perform code execution on a crafted software OVA image.","published":"2019-09-25T21:15:11.000Z","lastModified":"2026-06-17T02:15:10.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":6.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-347"],"affected":["cisco/ios xe","cisco/nx-os","cisco/nexus 3016 firmware","cisco/nexus 3048 firmware","cisco/nexus 3064 firmware","cisco/nexus 3064-t firmware","cisco/nexus 31108pc-v firmware","cisco/nexus 31108tc-v firmware","cisco/nexus 31128pq firmware","cisco/nexus 3132c-z firmware","cisco/nexus 3132q firmware","cisco/nexus 3132q-v firmware","cisco/nexus 3132q-xl firmware","cisco/nexus 3164q firmware","cisco/nexus 3172 firmware","cisco/nexus 3172pq-xl firmware","cisco/nexus 3172tq firmware","cisco/nexus 3172tq-32t firmware","cisco/nexus 3172tq-xl firmware","cisco/nexus 3232c firmware","cisco/nexus 3264c-e firmware","cisco/nexus 3264q firmware","cisco/nexus 3408-s firmware","cisco/nexus 34180yc firmware","cisco/nexus 34200yc-sm firmware","cisco/nexus 3432d-s firmware","cisco/nexus 3464c firmware","cisco/nexus 3524 firmware","cisco/nexus 3524-x firmware","cisco/nexus 3524-xl firmware","cisco/nexus 3548 firmware","cisco/nexus 3548-x firmware","cisco/nexus 3548-xl firmware","cisco/nexus 5548p firmware","cisco/nexus 5548up firmware","cisco/nexus 5596t firmware","cisco/nexus 5596up firmware","cisco/nexus 56128p firmware","cisco/nexus 5624q firmware","cisco/nexus 5648q firmware","cisco/nexus 5672up firmware","cisco/nexus 5696q firmware","cisco/nexus 6001 firmware","cisco/nexus 6004 firmware","cisco/nexus 7000 10-slot firmware","cisco/nexus 7000 18-slot firmware","cisco/nexus 7000 4-slot firmware","cisco/nexus 7000 9-slot firmware","cisco/nexus 7700 10-slot firmware","cisco/nexus 7700 18-slot firmware","cisco/nexus 7700 2-slot firmware","cisco/nexus 7700 6-slot firmware"],"epss":{"score":0.00306,"percentile":0.23301,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.31%).
