      "value": "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."

Espec\u00edficamente: todos los servidores web CODESYS basados en Microsoft Windows (tambi\u00e9n WinCE) que ejecutan la versi\u00f3n independiente 2.3 o que formen parte del sistema runtime CODESYS que ejecuta versiones anteriores a la V1.1.9.19. Una petici\u00f3n manipulada podr\u00eda provocar un desbordamiento de b\u00fafer y, por lo tanto, ejecutar c\u00f3digo arbitrario en el servidor web o desembocar en una condici\u00f3n de denegaci\u00f3n de servicio (DoS) debido a un cierre inesperado en el servidor web."
