As a part of EJBCA's domain security model, the peer connector allows the restriction of client certificates (for the RA, not the end user) to a limited set of allowed CAs, thus restricting the accessibility of that RA to the rights it has within a specific role. While this works for other protocols such as CMP, it was found that the EJBCA enrollment over an EST implementation bypasses this check, allowing enrollment with a valid client certificate through any functioning and authenticated RA connected to the CA. NOTE: an attacker must already have a trusted client certificate and authorization to enroll against the targeted CA.","severity":{"version":"3.1","score":4.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-11","score":0.00365,"percentile":0.30777,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-295"],"published":"2020-11-19T16:38:46Z","modified":"2026-09-08T08:47:12Z","fixes":[{"ecosystem":"Bitnami","package":"ejbca","fixed_in":["7.4.3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Bitnami","package":"ejbca","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.4.3"}]}]}],"products":[{"vendor":"primekey","product":"ejbca"}],"references":[{"url":"https://support.primekey.com/news/posts/40","tags":["x_refsource_MISC","x_transferred","Vendor Advisory","advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-28942","tags":["web"]},{"url":"https://github.com/advisories/GHSA-vjxv-h84w-vj5j"}],"sources":{"cve":[{"id":"CVE-2020-28942","description":"An issue exists in PrimeKey EJBCA before 7.4.3 when enrolling with EST while proxied through an RA over the Peers protocol.
