Summary

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.

Risk Assessment

An attacker can completely take over the device, potentially enabling network traffic interception, configuration modification, or using the device as an entry point into the network.

Recommendation

Apply available firmware updates from the manufacturer. Additionally, limit trust in devices on the local network and monitor TDDP traffic.
