The attacker must authenticate with valid administrator device credentials. The vulnerability is due to the incorrect implementation of a CLI command that allows a Bash command to be incorrectly invoked on the Guest Shell CLI. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Guest Shell prompt. A successful exploit could allow the attacker to issue commands that should be restricted by a Guest Shell account."},{"lang":"es","value":"na vulnerabilidad en la implementación Bash Shell para el software NX-OS de Cisco,  podría permitir a un atacante local autentificado omitir el conjunto de comandos limitados del Guest Shell y ejecutar comandos en el nivel de privilegio de un usuario administrador de la red fuera del Guest Shell. El atacante necesita autenticarse con credenciales de dispositivo de administrador válidas. La vulnerabilidad es debido a la implementación inapropiada de un comando de la CLI que permite que se invoque inapropiadamente un comando Bash en la CLI del Guest Shell. Un atacante podría explotar esta vulnerabilidad autentificándose en el dispositivo e introduciendo un comando creado en el indicador del Guest Shell. Una explotación exitosa podría permitir al atacante enviar comandos que deberían ser restringidos para una cuenta de Guest Shell."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.9}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","baseScore":6.0,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.2}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:C/I:C/A:C","baseScore":7.2,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"COMPLETE","integrityImpact":"COMPLETE","availabilityImpact":"COMPLETE"},"baseSeverity":"HIGH","exploitabilityScore":3.9,"impactScore":10.0,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-264"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:nx-os:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0\\(3\\)i4","versionEndExcluding":"7.0\\(3\\)i4\\(9\\)","matchCriteriaId":"3DFCC3C2-3483-4BD0-AF71-23574D0849B1"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:nx-os:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0\\(3\\)i7","versionEndExcluding":"7.0\\(3\\)i7\\(4\\)","matchCriteriaId":"EF06D835-FBE6-4866-B410-C2F66AEF68CD"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3000:-:*:*:*:*:*:*:*","matchCriteriaId":"10FFC5E8-CC5A-4D31-A63A-19E72EC442AB"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3100:-:*:*:*:*:*:*:*","matchCriteriaId":"41C14CC9-C244-4B86-AEA6-C50BAD5DA9A6"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3100-z:-:*:*:*:*:*:*:*","matchCriteriaId":"D14D4B4E-120E-4607-A4F1-447C7BF3052E"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3100v:-:*:*:*:*:*:*:*","matchCriteriaId":"15702ACB-29F3-412D-8805-E107E0729E35"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3200:-:*:*:*:*:*:*:*","matchCriteriaId":"32A532C0-B0E3-484A-B356-88970E7D0248"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3400:-:*:*:*:*:*:*:*","matchCriteriaId":"43913A0E-50D5-47DD-94D8-DD3391633619"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3500:-:*:*:*:*:*:*:*","matchCriteriaId":"A8E1073F-D374-4311-8F12-AD8C72FAA293"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3524-x:-:*:*:*:*:*:*:*","matchCriteriaId":"10F80A72-AD54-4699-B8AE-82715F0B58E2"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3524-xl:-:*:*:*:*:*:*:*","matchCriteriaId":"9354B6A2-D7D6-442E-BF4C-FE8A336D9E94"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3548-x:-:*:*:*:*:*:*:*","matchCriteriaId":"74CB4002-7636-4382-B33E-FBA060A13C34"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_3548-xl:-:*:*:*:*:*:*:*","matchCriteriaId":"10CEBF73-3EE0-459A-86C5-F8F6243FE27C"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_9000v:-:*:*:*:*:*:*:*","matchCriteriaId":"0CD9C1F1-8582-4F67-A77D-97CBFECB88B8"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_92160yc-x:-:*:*:*:*:*:*:*","matchCriteriaId":"4283E433-7F8C-4410-B565-471415445811"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_92300yc:-:*:*:*:*:*:*:*","matchCriteriaId":"F80AB6FB-32FD-43D7-A9F1-80FA47696210"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_92304qc:-:*:*:*:*:*:*:*","matchCriteriaId":"D5B2E4C1-2627-4B9D-8E92-4B483F647651"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_92348gc-x:-:*:*:*:*:*:*:*","matchCriteriaId":"557ED31C-C26A-4FAE-8B14-D06B49F7F08B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_9236c:-:*:*:*:*:*:*:*","matchCriteriaId":"11411BFD-3F4D-4309-AB35-A3629A360FB0"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_9272q:-:*:*:*:*:*:*:*","matchCriteriaId":"E663DE91-C86D-48DC-B771-FA72A8DF7A7C"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_93108tc-ex:-:*:*:*:*:*:*:*","matchCriteriaId":"A90184B3-C82F-4CE5-B2AD-97D5E4690871"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_93108tc-fx:-:*:*:*:*:*:*:*","matchCriteriaId":"4AB89849-6DA4-4C9D-BC3F-EE0E41FD1901"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:nexus_93120tx:-:*:*:*:*:*:*:*","m
