Command Injection in tmpServer Allows Local Privilege Escalation in TP-Link RE305

An
operating-system command injection vulnerability exists in the tmpServer
service of TP-Link RE305 V3. The service runs with root privileges and listens
on the local loopback interface. A local attacker with access to a
low-privileged process on the device may submit a crafted request to the TDDPv1
service and execute operating-system commands with root privileges.

Successful
exploitation may allow a local attacker with low privileges to obtain root
privileges and execute arbitrary operating-system commands on the affected
device.
