The vulnerability is due to insufficient validation of arguments passed to a specific VMAN CLI command on the affected device. An attacker who has administrator access to an affected device could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the device with root privileges, which may lead to complete system compromise.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":6.7},"cwes":["CWE-78","CWE-77"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-vman-cmd-injection","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-vman-cmd-injection"],"products":["cisco:ios_xe"],"source":"nvd","synced_at":"2026-10-19T20:59:10.855360465+00:00"},"epss":{"cve":"CVE-2019-12661","score":0.00449,"percentile":0.39045,"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).
