CVE-2024-51122Public exploitNetwork attack vector

Browser script execution via unescaped certificate fields

Published Feb 12, 2025 · Updated Mar 18, 2025

Cross-site scripting in Zertificon Z1 CertServer 3.16.4-2516-debian12 allows remote attackers to execute script via certificate fields. The certificate display renders ST, L, O, OU and CN values from a self-signed X.509 certificate without neutralizing HTML, so a closing div tag escapes the intended field. Exploitation requires a crafted certificate and a user to view its distinguished-name data; impact is limited to the viewer's browser context.
