Descriptions

Multiple system services installed alongside the Razer Synapse 3 software suite perform privileged operations on entries within the ChromaBroadcast subkey. These privileged operations consist of file name concatenation of a runtime log file that is used to store runtime log information. In other words, an attacker can create a file in an unintended directory (with some limitations).

Múltiples servicios del sistema instalados junto con el paquete de software Razer Synapse versión 3, llevan a cabo operaciones privilegiadas en las entradas dentro de la subclave ChromaBroadcast. Estas operaciones privilegiadas consisten en la concatenación de nombres de archivo de un archivo de registro de tiempo de ejecución que es usado para almacenar información de registro de tiempo de ejecución. En otras palabras, un atacante puede crear un archivo en un directorio no deseado (con algunas limitaciones)
