|---|
| विवरण | Netcore NBR200V2 firmware V1.3.241127.071246 contains a remotely triggerable buffer overflow in the WAN VLAN reconfiguration path. The firmware exposes both the routerd.wan_config_set ubus method and the uci ubus object for the network configuration. By first storing a crafted network.vlan_wanX.ports string and then invoking the WAN configuration handler, a remote attacker can drive the router into wan_config_set_vlan() and then set_ports_type(), where an unbounded strcat() writes into a 32-byte stack buffer. This can crash the process or, with a carefully shaped payload, lead to code execution. |
