      "value": "Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.6.0 until 4.14.6 and 5.0.0-beta3, DB::getFile() and DB::searchFile() in src/syscheckd/src/db/src/file.cpp concatenate a monitored file path into SQLite row filters. On non-Windows systems, FIMDBCreator::encodeString() does not escape the value. A local user who can create a filename in a File Integrity Monitoring directory can inject a UNION SELECT expression when wazuh-syscheckd processes or deletes that path. The confirmed primitive manipulates SELECT result sets consumed by the FIM code; stacked statements and remote code execution were not demonstrated. This issue is fixed in versions 4.14.6 and 5.0.0-beta3."

Desde la versión 4.6.0 hasta la 4.14.6 y la 5.0.0-beta3, DB::getFile() y DB::searchFile() en src/syscheckd/src/db/src/file.cpp concatenan una ruta de archivo monitoreada en los filtros de fila de SQLite. En sistemas que no son Windows, FIMDBCreator::encodeString() no escapa el valor. Un usuario local que puede crear un nombre de archivo en un directorio de Monitoreo de Integridad de Archivos puede inyectar una expresión UNION SELECT cuando wazuh-syscheckd procesa o elimina esa ruta. La primitiva confirmada manipula los conjuntos de resultados SELECT consumidos por el código FIM; las sentencias apiladas y la ejecución remota de código no fueron demostradas. Este problema está solucionado en las versiones 4.14.6 y 5.0.0-beta3."
