CUDY TR3000 · CVE-2026-75495 · Infrastructure
NO FIX YET · SEE WHAT TO DO
Cudy TR3000 routers before 2.5.42 let a malicious or compromised ACS (TR-069 management server) run shell commands as root through a crafted password value in SetParameterValues requests. An attacker who controls or hijacks the management server gets full root control of the router.

It reads this page and tells you if your code or app is affected.
Routers running Cudy TR3000 firmware before 2.5.42 with TR-069 remote management enabled are exposed, since the flaw is reached through the management server's SetParameterValues requests. Devices with remote management disabled or without an ACS configured are much less exposed; the sources do not say whether the default configuration has TR-069 on.
Not affected if firmware-2.5.42-or-later, tr-069-disabled

2.5.42.2.5.42 or later.Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying a crafted InternetGatewayDevice.User.{i}.Password value. Attackers can send a SetParameterValues request with shell metacharacters that obuspa_system.lua concatenates into a luci.util.exec() command string, gaining root command execution.
