Exploit públicoNo conocidosin código público localizado

Se ha descubierto una vulnerabilidad en DrayTek Vigor2960 1.5.1.6 Revision 8218. Afecta a la función uploadlangs del archivo /cgi-bin/mainfunction.cgi del componente Upload Endpoint. Dicha manipulación provoca una inyección de comandos. El ataque puede ejecutarse de forma remota. El exploit se ha hecho público y puede utilizarse. Actualizar a la versión 1.5.1.7 permite mitigar este problema. Se recomienda actualizar el componente afectado. El fabricante explica: "2960 1.5.1.7 ha corregido muchos problemas de seguridad. Y 2960 está en EoS con soporte limitado, solo se revisarán los problemas importantes (p. ej., vulnerabilidades sin autenticar)." Esta vulnerabilidad solo afecta a productos que el fabricante ya no soporta.
