CVE-2026-36741
U-SPEED AC1200 Gigabit Wi-Fi Router (Model: T18-21K) V1.0 is vulnerable to Command Injection.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
U-SPEED AC1200 Gigabit Wi-Fi Router (Model: T18-21K) V1.0 is vulnerable to Command Injection. The Network Time Protocol (NTP) configuration interface does not properly sanitize user-supplied input. An authenticated user with permission to configure NTP settings can inject arbitrary system commands through crafted input fields. These commands are executed with elevated privileges, leading to potential full system compromise.
