To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of the resources loaded by the application at run time. An attacker could exploit this vulnerability by crafting a malicious DLL file and placing it in a specific location on the targeted system. The malicious DLL file would execute when the vulnerable application is launched. A successful exploit could allow the attacker to execute arbitrary code on the target machine with the privileges of another user account.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","score":5.3},"cwes":["CWE-427"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191120-webex-teams-dll","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191120-webex-teams-dll"],"products":["cisco:webex_meetings","cisco:webex_teams"],"source":"nvd","synced_at":"2026-10-19T20:59:25.448946135+00:00"},"epss":{"cve":"CVE-2019-16001","score":0.00377,"percentile":0.31672,"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).
