DescriptionWe found an stack overflow vulnerability in D-Link Technology NAS device with firmware which was released recently, allows remote attackers to crash the server.In Local_Backup_Info function, f_idx is directly passed by the attacker, If this part of the data is too long, it will cause the stack overflow, so we can control the f_idx to execute arbitrary code.
