CVE-2022-42954Network attack vector

Stored XSS via unescaped certificate subject fields

Published Nov 17, 2022 · Updated Apr 30, 2025

Stored XSS in Keyfactor EJBCA before 7.10.0 allows remote authenticated users to run script in an RA Web user's browser. The RA Web end-entity and certificate search pages render subject fields without proper escaping. Exploitation requires an untrusted client to control subject fields through an RA-mode protocol or CSR subject-DN override and another RA Web user to view the stored result.
