O problema decorre do tratamento inadequado, por parte do Windows, das chamadas para o Advanced Local Procedure Call (ALPC), levando a uma elevação de privilégios. Um invasor que explore com sucesso essa vulnerabilidade poderá executar código arbitrário no contexto de segurança do sistema local. Isso permite que os invasores afetem o sistema, potencialmente elevando seus privilégios.

A security issue exists due to Microsoft Edge's improper handling of redirect requests. This allows an attacker to bypass Cross-Origin Resource Sharing (CORS) restrictions. By exploiting this, an attacker could force the browser to send restricted data to a website of their choice using a specially crafted webpage.

The issue is caused by a buffer overflow in memory due to improper handling of JavaScript scripts by the ChakraCore engine and Microsoft Edge browser. This could allow a remote attacker to execute arbitrary code using specially crafted web page content. The vulnerability can corrupt memory, enabling an attacker to execute code in the context of the current user. If the user has administrative rights, the attacker could gain control of the affected system, allowing them to install programs, view, change, or delete data, or create new accounts with full user rights.
