Nagios XI versions prior to 5.7.3 contain a command injection vulnerability in the report PDF download/export functionality. User-supplied values used in the PDF generation pipeline or the wrapper that invokes offline/pdf helper utilities were insufficiently validated or improperly escaped, allowing an authenticated attacker who can trigger PDF exports to inject shell metacharacters or arguments.

Summary		(es) Las versiones de Nagios XI anteriores a la 5.7.3 contienen una vulnerabilidad de inyección de comandos en la funcionalidad de descarga/exportación de informes PDF. Los valores proporcionados por el usuario utilizados en la cadena de generación de PDF o el envoltorio que invoca las utilidades auxiliares sin conexión/PDF no fueron validados suficientemente o se escaparon incorrectamente, permitiendo a un atacante autenticado que puede activar exportaciones de PDF inyectar metacaracteres o argumentos de shell.
