Linksys RE6250/RE6300/RE6350/RE6500/RE7000/RE9000 DHCPReserveAddGroup stack-based overflow

A vulnerability was determined in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function DHCPReserveAddGroup of the file /goform/DHCPReserveAddGroup. This manipulation of the argument enable_group/name_group/ip_group/mac_group causes stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
