The Web Interfaces (Admin, Userweb, Sidechannel) can use different methods to perform the authentication of a user. A specific authentication method during login does not check the provided data (when a certain manipulation occurs) and returns OK for any authentication request. This allows an attacker to login to the admin panel as a user of his choice, e.g., the root user (with highest privileges) or even a non-existing user.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-306"],"references":["https://kunde.genua.de/en/overview/genugate.html","https://sec-consult.com/vulnerability-lab/advisory/authentication-bypass-genua-genugate/","https://www.genua.de/en/it-security-solutions/high-resistance-firewall-genugate","https://kunde.genua.de/en/overview/genugate.html","https://sec-consult.com/vulnerability-lab/advisory/authentication-bypass-genua-genugate/"],"products":["genua:genuagate"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-27215","score":0.02349,"percentile":0.83692,"date":"2026-11-01"},"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).
