CVE-2024-50859Public exploitNetwork attack vector

Administrator-session script execution via unescaped import errors

Published Jan 14, 2025 · Updated Jan 15, 2025

Reflected XSS in GestioIP 3.5.7 allows context-dependent attackers to execute script via a malformed ACL connection import file. The ip_import_acl_csv handler returns uploaded file content in an HTML error response without output encoding when parsing fails. An authenticated administrator must enable ACL connection management and upload the file; script runs in that administrator's browser and can read application data.
