CVE-2024-7397Public exploitNetwork attack vector

Root command execution via unfiltered management settings

Published Aug 5, 2024 · Updated Nov 4, 2025

Command injection in Korenix JetPort 5601v3 through 1.2 allows remote attackers to execute arbitrary commands as root over the network. The ser2net binary receives attacker-controlled setting values through the unauthenticated TCP 600 telnet service and inserts them into system() arguments without filtering shell metacharacters. Network reachability of TCP 600 is sufficient; injected commands run as root and permit full control of the appliance.
