CVE-2026-102815
Command Injection in tmpServer Allows Local Privilege Escalation in TP-Link RE305
Description
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.
