Descriptions

This affects the package @aws-sdk/shared-ini-file-loader before 1.0.0-rc.9; the package aws-sdk before 2.814.0. If an attacker submits a malicious INI file to an application that parses it with loadSharedConfigFiles , they will pollute the prototype on the application. This can be exploited further depending on the context.

Esto afecta al paquete @aws-sdk/shared-ini-file-loader versiones anteriores a 1.0.0-rc.9; el paquete aws-sdk versiones anteriores a 2.814.0. Si un atacante envía un archivo INI malicioso hacia una aplicación que lo analiza con la función loadSharedConfigFiles, contaminará el prototipo de la aplicación. Esto puede ser explotado aún más dependiendo del contexto
