CVE-2026-102815 (GCVE-0-2026-102815)

Vulnerability from cvelistv5 – Published: 2026-10-27 17:40 – Updated: 2026-10-27 17:40

Title

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

Summary

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.

Severity

6.9 (Medium)


                        
                          CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N

CWE

CWE-78 - Improper neutralization of special elements used in an OS command ('OS command injection')
