ZDI-CAN-9650: (Pwn2Own) TP-Link Archer A7 tdpServer Command Injection Remote Code Execution Vulnerability
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer A7 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the tdpServer service, which listens on UDP port 20002 by default. When parsing the slavemac parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the root user.
