CVE-2025-9619Network attack vector

Unauthenticated data exposure via unrestricted DANFE identifier

Published Aug 29, 2025 · Updated Aug 29, 2025

Resource injection in E4 Sistemas Mercatus ERP 2.00.019 allows remote attackers to read data referenced by a crafted DANFE identifier. The undisclosed handler at /basico/webservice/imprimir-danfe/id/ uses an attacker-controlled ID without properly restricting the referenced resource. The endpoint is remotely reachable without authentication or user interaction, and the published impact is limited to data exposure.
