Descriptions

Softing Secure Integration Server Exposure of Resource to Wrong Sphere Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Softing Secure Integration Server. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

The specific flaw exists within the handling of OPC FileDirectory namespaces. The issue results from the lack of proper validation of user-supplied data before using it to create a server object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20547.

Softing Secure Integration Server Exposición de recursos a una vulnerabilidad de ejecución remota de código de esfera incorrecta. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de Softing Secure Integration Server. Aunque se requiere autenticación para aprovechar esta vulnerabilidad, se puede omitir el mecanismo de autenticación existente. La falla específica existe en el manejo de espacios de nombres OPC FileDirectory. El problema se debe a la falta de validación adecuada de los datos proporcionados por el usuario antes de usarlos para crear un objeto de servidor. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código arbitrario en el contexto de la raíz. Era ZDI-CAN-20547.
