CVE-2019-25259Public exploitNetwork attack vector

Administrative account creation via unchecked cross-origin POST

Published Jan 7, 2026 · Updated Jan 7, 2026

Cross-site request forgery in Leica GR10/GR25/GR30/GR50 GNSS firmware allows attackers to create administrative users remotely. The config_UserManagementPostBackHelper.lsp endpoint accepts username, password, and webRole fields in a cross-origin POST without validating request intent. Versions 1.00.395, 2.62.782, 3.10.1633, 3.22.1818, 4.11.606, 4.20.232, and 4.30.063 are affected, and a logged-in user must visit an attacker-controlled page.
