| 标题 | LB-LINK（深圳必联电子） B-Link AC1200 X-PRO(AC6)_Dual_V1.0.22-20231206-upgrade.bin Hardcoded Credentials |
|---|
| 描述 | The B-Link X-PRO(AC6) firmware includes a pre-configured TR-069 remote management daemon (easycwmp) with three sets of hardcoded credentials for local interface, ACS (Auto-Configuration Server), and STUN server access. The configuration also discloses production server URLs and IP addresses. While TR-069 is disabled by default (option enable '0'), an attacker who gains any level of access to the admin panel can enable it and use the hardcoded credentials to establish a remote management channel, potentially allowing persistent C2 communication and configuration manipulation from the manufacturer's cloud infrastructure — or a rogue server impersonating it. |
