Exploit públicoNo conocidosin código público localizado

Se ha identificado una debilidad en DrayTek Vigor2960 1.5.1.6 Revision 8218. El elemento afectado es la función rename_table del archivo /cgi-bin/mainfunction.cgi del componente Rename Table Handler. Esta manipulación del argumento newtable provoca una inyección de comandos. El ataque puede iniciarse de forma remota. El exploit se ha hecho público y podría utilizarse en ataques. Actualizar a la versión 1.5.1.7 es suficiente para resolver este problema. Se recomienda actualizar el componente afectado. El fabricante explica: "2960 1.5.1.7 has corrected many security issues. And 2960 is EoS with limited support, only major issues would be reviewed(e.g. unauthenticated vuln.)". Esta vulnerabilidad solo afecta a productos que ya no reciben soporte por parte del fabricante.
