Descriptions

A Stack-based Buffer Overflow issue was discovered in 3S-Smart CODESYS Web Server. Specifically: all Microsoft Windows (also WinCE) based CODESYS web servers running stand-alone Version 2.3, or as part of the CODESYS runtime system running prior to Version V1.1.9.19. A crafted request may cause a buffer overflow and could therefore execute arbitrary code on the web server or lead to a denial-of-service condition due to a crash in the web server.

Se ha descubierto un problema de desbordamiento de búfer basado en pila en 3S-Smart CODESYS Web Server. Específicamente: todos los servidores web CODESYS basados en Microsoft Windows (también WinCE) que ejecutan la versión independiente 2.3 o que formen parte del sistema runtime CODESYS que ejecuta versiones anteriores a la V1.1.9.19. Una petición manipulada podría provocar un desbordamiento de búfer y, por lo tanto, ejecutar código arbitrario en el servidor web o desembocar en una condición de denegación de servicio (DoS) debido a un cierre inesperado en el servidor web.
