Affected: TP-Link Systems Inc. Archer AX90 v1

A command injection vulnerability exists in the TDDPv2 service (/usr/bin/tddp) on Archer AX90 V1. An unauthenticated adjacent-network attacker can exploit the setProductVer command handler to execute arbitrary operating system commands as root during device boot.

Successful exploitation may result in complete device compromise through arbitrary command execution with root privileges.
