The attacker requires valid device credentials. This vulnerability exists because proper role-based access control (RBAC) filters are not applied to file download actions. An attacker could exploit this vulnerability by logging in to the application and then navigating to the directory listing and download functions. A successful exploit could allow the attacker to download sensitive files that should be restricted, which could result in disclosure of sensitive information.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-552"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-insight-infodis-2By2ZpBB","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-insight-infodis-2By2ZpBB"],"products":["cisco:nexus_insights"],"source":"nvd","synced_at":"2026-10-19T21:21:57.125947417+00:00"},"epss":{"cve":"CVE-2021-34765","score":0.00873,"percentile":0.58913,"date":"2026-10-31"},"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).
