CVE-2016-20045

HNB Organizer 1.9.18-10 contains a local buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized argument to the -rc command-line parameter. Attackers can craft a malicious input string exceeding 108 bytes containing shellcode and a return address to overwrite the stack and achieve code execution.

Summary		(es) HNB Organizer 1.9.18-10 contiene una vulnerabilidad de desbordamiento de búfer local que permite a atacantes locales ejecutar código arbitrario al proporcionar un argumento de tamaño excesivo al parámetro de línea de comandos -rc. Los atacantes pueden crear una cadena de entrada maliciosa que exceda los 108 bytes que contenga shellcode y una dirección de retorno para sobrescribir la pila y lograr la ejecución de código.
