What is CVE-2026-75577?

The Cudy TR3000 router, prior to version 2.5.42, is susceptible to a command injection vulnerability that can be exploited by authenticated administrators. By crafting a malicious WireGuard private key and leveraging the vpn.export_conf method accessible on the /cgi-bin/luci/rpc/app JSON-RPC endpoint, an attacker can pass a specially crafted private_key containing shell metacharacters into the wg pubkey command. This flaw could allow unauthorized execution of arbitrary commands with root privileges, posing significant risks to the device's integrity and the network it manages.
