CVE-2024-53977

A vulnerability has been identified in ModelSim (All versions < V2025.1), Questa (All versions < V2025.1). An example setup script contained in affected applications allows a specific executable file to be loaded from the current working directory. This could allow an authenticated local attacker to inject arbitrary code and escalate privileges in installations where administrators or processes with elevated privileges launch the script from a user-writable directory.

Summary		(es) Se ha identificado una vulnerabilidad en ModelSim (todas las versiones anteriores a la V2025.1) y Questa (todas las versiones anteriores a la V2025.1). Un ejemplo de secuencia de comandos de configuración incluido en las aplicaciones afectadas permite cargar un archivo ejecutable específico desde el directorio de trabajo actual. Esto podría permitir que un atacante local autenticado inyecte código arbitrario y aumente los privilegios en instalaciones en las que los administradores o procesos con privilegios elevados inicien la secuencia de comandos desde un directorio en el que el usuario pueda escribir.
