The vulnerabilities are due to improper boundary checks for certain user-supplied input. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the API subsystem of an affected system. When this request is processed, an exploitable buffer overflow condition may occur. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying operating system (OS).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-20","CWE-119"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucs-api-rce-UXwpeDHd","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucs-api-rce-UXwpeDHd"],"products":["cisco:enterprise_nfv_infrastructure_software","cisco:integrated_management_controller"],"source":"nvd","synced_at":"2026-10-19T21:11:20.317016139+00:00"},"epss":{"cve":"CVE-2020-3470","score":0.04798,"percentile":0.91945,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
