It is possible to include a UNC path in the OpenVPN configuration file when referencing file paths for parameters (such as auth-user-pass). When this file is imported and the client attempts to validate the file path, it performs an open operation on the path and leaks the user's Net-NTLMv2 hash to an external server. This could be exploited by having a user open a crafted malicious ovpn configuration file.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","score":5.0},"cwes":["CWE-200"],"references":["https://github.com/RhinoSecurityLabs/CVEs","https://rhinosecuritylabs.com/aws/cve-2022-25165-aws-vpn-client/","https://github.com/RhinoSecurityLabs/CVEs","https://rhinosecuritylabs.com/aws/cve-2022-25165-aws-vpn-client/"],"products":["amazon:aws_client_vpn"],"source":"nvd","synced_at":"2026-10-19T21:30:03.577988018+00:00"},"epss":{"cve":"CVE-2022-25166","score":0.01466,"percentile":0.73684,"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).
