{"schema":"threatline.record/2","record":{"id":"CVE-2026-76471","aliases":[],"summary":"Cisco NX-OS Software NX-API Remote Code Execution Vulnerability","details":"A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device. \r\n\r\nThe vulnerability is due to insufficient input validation of data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition.","categories":["Network & edge"],"product":"Cisco NX-OS Software","vendor":"Cisco","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-76471","source_modified_at":"2026-10-08T03:55:32.792Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Cisco NX-OS Software","vendor":"Cisco","versions":[{"version":"9.2(3)","status":"affected"},{"version":"9.2(2v)","status":"affected"},{"version":"9.2(1)","status":"affected"},{"version":"9.2(2t)","status":"affected"},{"version":"9.2(3y)","status":"affected"},{"version":"9.3(2)","status":"affected"},{"version":"9.2(4)","status":"affected"},{"version":"9.3(1)","status":"affected"},{"version":"9.3(1z)","status":"affected"},{"version":"9.2(2)","status":"affected"},{"version":"9.3(3)","status":"affected"},{"version":"9.3(4)","status":"affected"},{"version":"9.3(5)","status":"affected"},{"version":"9.3(6)","status":"affected"},{"version":"9.3(5w)","status":"affected"},{"version":"9.3(7)","status":"affected"},{"version":"9.3(7k)","status":"affected"},{"version":"9.3(7a)","status":"affected"},{"version":"9.3(8)","status":"affected"},{"version":"9.3(9)","status":"affected"},{"version":"9.3(10)","status":"affected"},{"version":"10.3(1)","status":"affected"},{"version":"10.3(2)","status":"affected"},{"version":"9.3(11)","status":"affected"},{"version":"10.3(3)","status":"affected"},{"version":"9.3(12)","status":"affected"},{"version":"10.4(1)","status":"affected"},{"version":"10.3(99w)","status":"affected"},{"version":"10.3(3w)","status":"affected"},{"version":"10.3(99x)","status":"affected"}],"defaultStatus":"unknown"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-76471","source_modified_at":"2026-10-08T03:55:32.792Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Cisco Unified Computing System (Managed)","vendor":"Cisco","versions":[{"version":"4.0(1a)","status":"affected"},{"version":"4.1(1d)","status":"affected"},{"version":"4.0(4f)","status":"affected"},{"version":"4.0(4a)","status":"affected"},{"version":"4.0(4e)","status":"affected"},{"version":"4.0(4c)","status":"affected"},{"version":"4.0(4h)","status":"affected"},{"version":"4.1(1c)","status":"affected"},{"version":"4.0(2a)","status":"affected"},{"version":"4.1(1e)","status":"affected"},{"version":"4.1(2a)","status":"affected"},{"version":"4.0(2b)","status":"affected"},{"version":"4.0(1b)","status":"affected"},{"version":"4.0(4d)","status":"affected"},{"version":"4.0(2e)","status":"affected"},{"version":"4.1(1a)","status":"affected"},{"version":"4.0(4g)","status":"affected"},{"version":"4.0(1c)","status":"affected"},{"version":"4.0(1d)","status":"affected"},{"version":"4.0(4b)","status":"affected"},{"version":"4.0(4i)","status":"affected"},{"version":"4.0(2d)","status":"affected"},{"version":"4.1(1b)","status":"affected"},{"version":"4.1(2b)","status":"affected"},{"version":"4.0(4k)","status":"affected"},{"version":"4.1(3a)","status":"affected"},{"version":"4.1(3b)","status":"affected"},{"version":"4.1(2c)","status":"affected"},{"version":"4.0(4l)","status":"affected"},{"version":"4.1(4a)","status":"affected"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00523,"percentile":0.4356,"score_date":"2026-10-23"},"published_at":"2026-10-07T16:15:35.076Z","modified_at":"2026-10-08T03:55:32.792Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-76471","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T03:55:32.792Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-76471","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-napi-rce-r2shwu2j"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-07T00:00:00+00:00"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-08T03:55:32.792Z","content_hash":"bac9a001a11bd754ff721741bd2675ebcfa0c4d327194ae1c00266a39b1e2f3a"}}
