Descriptions

A Stack Buffer Overflow issue was discovered in 3S-Smart Software Solutions GmbH CODESYS Web Server. The following versions of CODESYS Web Server, part of the CODESYS WebVisu web browser visualization software, are affected: CODESYS Web Server Versions 2.3 and prior. A malicious user could overflow the stack buffer by providing overly long strings to functions that handle the XML. Because the function does not verify string size before copying to memory, the attacker may then be able to crash the application or run arbitrary code.

Se detectó un problema de desbordamiento del búfer de pila en el Servidor Web de 3S-Smart Software Solutions GmbH CODESYS. Las siguientes versiones del Servidor Web de CODESYS, parte del software de visualización del navegador web WebVisu de CODESYS, están afectadas: el Servidor Web de CODESYS versiones 2.3 y anteriores. Un usuario malicioso podría desbordar el búfer de pila al proporcionar cadenas demasiado largas en las funciones que manejan el XML. Por que la función no comprueba el tamaño de la cadena antes de copiar en la memoria, el atacante puede bloquear la aplicación o ejecutar un código arbitrario.
