The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level by executing commands that should be restricted to other roles. For example, a dev-ops user could escalate their privilege level to admin with a successful exploit of this vulnerability.","A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by e...","2019-03-06T22:29:00.293","2020-10-08T19:29:26.42",7.8,"CVSS:3.1\u002FAV:L\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":29,"CVSSMetricV2":36,"CVSSMetricV40":26},[16],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":27,"ImpactScore":28},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":25,"AvailabilityImpact":25,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":25,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.1","LOCAL","LOW","NONE","UNCHANGED","HIGH",null,1.8,5.9,[30],{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":27,"ImpactScore":28},"ykramarz@cisco.com","Secondary",{"Version":34,"VectorString":35,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":25,"AvailabilityImpact":25,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.0","CVSS:3.0\u002FAV:L\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",[37],{"Source":17,"Type":18,"CVSSData":38,"BaseSeverity":25,"ExploitabilityScore":43,"ImpactScore":44,"ACInsufInfo":26,"ObtainAllPrivilege":26,"ObtainUserPrivilege":26,"ObtainOtherPrivilege":26,"UserInteractionRequired":26},{"Version":39,"VectorString":40,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":41,"IntegrityImpact":41,"AvailabilityImpact":41,"BaseScore":42,"BaseSeverity":26,"Exploitability":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"CollateralDamagePotential":26,"TargetDistribution":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"EnvironmentalScore":26},"2.0","AV:L\u002FAC:L\u002FAu:N\u002FC:C\u002FI:C\u002FA:C","COMPLETE",7.2,3.9,10,0.00386,[45,45,45,45,45,45,45],"High",[49,54,58,61,64,67,70,73,76],{"vendor":50,"product":51,"version":52,"criteria":53,"vulnerable":4},"cisco","nx-os","*","cpe:2.3:o:cisco:nx-os:*:*:*:*:*:*:*:*",{"vendor":50,"product":55,"version":56,"criteria":57,"vulnerable":4},"nexus_3000","-","cpe:2.3:h:cisco:nexus_3000:-:*:*:*:*:*:*:*",{"vendor":50,"product":59,"version":56,"criteria":60,"vulnerable":4},"nexus_3500","cpe:2.3:h:cisco:nexus_3500:-:*:*:*:*:*:*:*",{"vendor":50,"product":62,"version":56,"criteria":63,"vulnerable":4},"nexus_3600","cpe:2.3:h:cisco:nexus_3600:-:*:*:*:*:*:*:*",{"vendor":50,"product":65,"version":56,"criteria":66,"vulnerable":4},"nexus_7000","cpe:2.3:h:cisco:nexus_7000:-:*:*:*:*:*:*:*",{"vendor":50,"product":68,"version":56,"criteria":69,"vulnerable":4},"nexus_7700","cpe:2.3:h:cisco:nexus_7700:-:*:*:*:*:*:*:*",{"vendor":50,"product":71,"version":56,"criteria":72,"vulnerable":4},"nexus_9000_in_aci_mode","cpe:2.3:h:cisco:nexus_9000_in_aci_mode:-:*:*:*:*:*:*:*",{"vendor":50,"product":74,"version":56,"criteria":75,"vulnerable":4},"nexus_9000_in_standalone","cpe:2.3:h:cisco:nexus_9000_in_standalone:-:*:*:*:*:*:*:*",{"vendor":50,"product":77,"version":52,"criteria":78,"vulnerable":4},"nexus_9500","cpe:2.3:h:cisco:nexus_9500:*:*:*:*:*:*:*:*",9,[81,87],{"url":82,"source":83,"tags":84},"http:\u002F\u002Fwww.securityfocus.com\u002Fbid\u002F107324","Securityfocus",[85,86],"Third Party Advisory","VDB Entry",{"url":88,"source":89,"tags":90},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-20190306-nx-os-bash-escal","Cisco",[91,92],"Patch","Vendor Advisory",2,[95,98],{"id":96,"name":96,"description":97},"Unknown","NVD-CWE-noinfo",{"id":96,"name":96,"description":99},"CWE-264",false,[],{"title":103,"metaDescription":104,"keywords":105,"canonicalUrl":106,"structuredData":107},"What is CVE-2019-1593?
