The vulnerability is due to insufficient sanitization of user-supplied input when issuing a specific CLI command with parameters on an affected device. An attacker could exploit this vulnerability by authenticating to the device CLI and issuing certain commands. A successful exploit could allow the attacker to escape the restricted shell and execute arbitrary commands with root-level privileges on the affected device. This vulnerability only affects Cisco Nexus 9000 Series ACI Mode Switches that are running a release prior to 14.0(3d).","severity":{"version":"3.0","score":7.8,"vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.00503,"percentile":0.43319,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-264","CWE-78"],"published":"2019-03-06T22:00:00Z","modified":"2026-06-17T02:28:48Z","products":[{"vendor":"cisco","product":"cisco nx-os software for nexus 9000 series fabric switches aci mode"},{"vendor":"cisco","product":"nx-os"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-shell-escape","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Patch","Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/107311","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1591"},{"url":"https://github.com/advisories/GHSA-9285-57jw-cj77"}],"sources":{"cve":[{"id":"CVE-2019-1591","title":"Cisco Nexus 9000 Series Fabric Switches Application Centric Infrastructure Mode Shell Escape Vulnerability","description":"A vulnerability in a specific CLI command implementation of Cisco Nexus 9000 Series ACI Mode Switch Software could allow an authenticated, local attacker to escape a restricted shell on an affected device.
