Unauthenticated database compromise via id_concesion injection

Published Jul 8, 2025 · Updated Jul 10, 2025

SQL injection in Quiter Gateway before 4.7.0 allows remote attackers to read, create, update, and delete databases over the network. The /FacturaE/VerFacturaPDF endpoint fails to neutralize SQL syntax in the id_concesion parameter before using it in a database operation. No authentication or user interaction is required, and successful requests can disclose or alter database contents or interrupt service by deleting data.
