CVE-2026-129102

Description

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root by injecting newlines into the IPsec keyexchange field of the vpn.set_conf RPC method. Attackers can append a second leftupdown directive to ipsec.conf, which StrongSwan's updown plugin runs as root when an attacker-controlled peer establishes the CHILD_SA.
