Calero VeraSMART versions prior to 2022 R1 use static ASP.NET/IIS machineKey values configured for the VeraSMART web application and stored in C:\\Program Files (x86)\\Veramark\\VeraSMART\\WebRoot\\web.config. An attacker who obtains these keys can craft a valid ASP.NET ViewState payload that passes integrity validation and is accepted by the application, resulting in server-side deserialization and remote code execution in the context of the IIS application.
Calero VeraSMART versions prior to 2022 R1 use static ASP.NET/IIS machineKey values configured for the VeraSMART web application and stored in C:\\Program Files (x86)\\Veramark\\VeraSMART\\WebRoot\\web.config. An attacker who obtains these keys can craft a valid ASP.NET ViewState payload that passes integrity validation and is accepted by the application, resulting in server-side deserialization and remote code execution in the context of the IIS application.
Las versiones de Calero VeraSMART anteriores a 2022 R1 utilizan valores estáticos de machineKey de ASP.NET/IIS configurados para la aplicación web VeraSMART y almacenados en C:\\Program Files (x86)\\Veramark\\VeraSMART\\WebRoot\\web .config. Un atacante que obtiene estas claves puede crear una carga útil de ViewState de ASP.NET válida que pasa la validación de integridad y es aceptada por la aplicación, lo que resulta en deserialización del lado del servidor y ejecución remota de código en el contexto de la aplicación IIS.
