{"id":"CVE-2019-1591","state":"PUBLISHED","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. 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).","publishedAt":"2019-03-06T22:00:00.000Z","updatedAt":"2024-11-20T17:27:22.076Z","severity":{"score":7.8,"label":"High","version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco NX-OS Software for Nexus 9000 Series Fabric Switches ACI Mode"],"affected":[{"vendor":"Cisco","product":"Cisco NX-OS Software for Nexus 9000 Series Fabric Switches ACI Mode","versions":[{"version":"14.0(3d)","status":"affected"}]}],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-aci-shell-escape","http://www.securityfocus.com/bid/107311"],"weaknesses":["CWE-264"],"ingestedAt":"2026-10-29T19:45:46.792Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2019/1xxx/CVE-2019-1591.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2019-1591","state":"PUBLISHED","datePublished":"2019-03-06T22:00:00.000Z","dateUpdated":"2024-11-20T17:27:22.076Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2018-12-06T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco Nexus 9000 Series Fabric Switches Application Centric Infrastructure Mode Shell Escape Vulnerability","descriptions":[{"lang":"en","value":"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.
