The vulnerability is due to insufficient validation of requests sent to the REST API. An attacker could exploit this vulnerability by sending a crafted request to the REST API. A successful exploit could allow the attacker to cause a permanent DoS condition that is due to high CPU utilization. Manual intervention may be required to recover the Cisco IND.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-20"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ind-dos-BwG634zn","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ind-dos-BwG634zn"],"products":["cisco:industrial_network_director","cisco:network_level_service"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-3567","score":0.01154,"percentile":0.66999,"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).
