On startup, the PIA Windows service (pia-service.exe) loads the OpenSSL library from %PROGRAMFILES%\\Private Internet Access\\libeay32.dll. This library attempts to load the C:\\etc\\ssl\\openssl.cnf configuration file which does not exist. By default on Windows systems, authenticated users can create directories under C:\\. A low privileged user can create a C:\\etc\\ssl\\openssl.cnf configuration file to load a malicious OpenSSL engine library resulting in arbitrary code execution as SYSTEM when the service starts.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-427"],"references":["https://blog.mirch.io/2019/06/10/cve-2019-12572-pia-windows-privilege-escalation-malicious-openssl-engine/","https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12572.txt","https://blog.mirch.io/2019/06/10/cve-2019-12572-pia-windows-privilege-escalation-malicious-openssl-engine/","https://github.com/mirchr/security-research/blob/master/vulnerabilities/PIA/CVE-2019-12572.txt"],"products":["londontrustmedia:private_internet_access"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2019-12572","score":0.00934,"percentile":0.60761,"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).
