Also, it creates a WindScribeService.exe system process that establishes a \\\\.\\pipe\\WindscribeService named pipe endpoint that allows the Windscribe VPN process to connect and execute an OpenVPN process or other processes (like taskkill, etc.). There is no validation of the program name before constructing the lpCommandLine argument for a CreateProcess call. An attacker can run any malicious process with SYSTEM privileges through this named pipe.","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-20"],"references":["http://packetstormsecurity.com/files/156222/Windscribe-WindscribeService-Named-Pipe-Privilege-Escalation.html","http://sqlulz.blogspot.com/2018/05/windscribe-vpn-privilege-escalation.html","http://packetstormsecurity.com/files/156222/Windscribe-WindscribeService-Named-Pipe-Privilege-Escalation.html","http://sqlulz.blogspot.com/2018/05/windscribe-vpn-privilege-escalation.html"],"products":["windscribe:windscribe"],"source":"nvd","synced_at":"2026-10-19T20:50:40.212176939+00:00"},"epss":{"cve":"CVE-2018-11479","score":0.09756,"percentile":0.95528,"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).
