CVE-2023-34196Network attack vector

Certificate disclosure and service interruption via improper authentication

Published Aug 3, 2023 · Updated Oct 17, 2024

Improper authentication in Keyfactor EJBCA before 8.0.0 allows remote attackers to interrupt certificate distribution or disclose CA certificates. Keyfactor identifies /ejbca/ra/cert as the affected servlet but has not published the specific authentication operation that mishandles requests. Exposure requires reachable RA Web; disclosure also requires OAuth and separated CA visibility, while blocking the URL or disabling RA Web prevents access.
