Mirai botnet started exploiting the CVE-2023-1389 vulnerability (aka ZDI-CAN-19557/ZDI-23-451) in TP-Link Archer A21 in recent attacks.
Last week, the Zero Day Initiative (ZDI) threat-hunting team observed the Mirai botnet attempting to exploit the CVE-2023-1389 vulnerability (aka ZDI-CAN-19557/ZDI-23-451, CVSS v3: 8.8) in TP-Link Archer AX21 Wi-Fi routers.
The CVE-2023-1389 flaw is an unauthenticated command injection vulnerability that resides in the locale API of the web management interface of the TP-Link Archer AX21 router. The root cause of the problem is the lack of input sanitization in the locale API that manages the router’s language settings. A remote attacker can trigger the issue to inject commands that should be executed on the device.
