|---|
| Описание | Netcore NBR200V2 firmware V1.3.241127.071246 contains a remotely triggerable buffer overflow in vlan_load_form_uci(). The firmware exposes uci write operations for the network configuration and also exposes routerd.wan_num_set over /ubus. By remotely planting an oversized named switch_vlan section in the network configuration and then invoking the WAN-number reconfiguration logic, an attacker can force vlan_load_form_uci() to copy the overlong section name into a heap allocation with only 36 bytes of remaining space. This can crash the process or, with a crafted payload, lead to arbitrary code execution through heap corruption. |
