Exploitation Summary

EIP tracks 2 public exploits for CVE-2020-10884. PoCs published by Metasploit, including Metasploit module exploits/linux/misc/tplink_archer_a7_c7_lan_rce.

AI-analyzed exploit summary This Metasploit module exploits a command injection vulnerability in the tdpServer daemon on TP-Link Archer A7/C7 routers, allowing unauthenticated remote code execution as root via a crafted UDP packet on port 20002.

Description

This vulnerability allows network-adjacent attackers execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 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. This issue results from the use of hard-coded encryption key. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-9652.
