CVE-2026-75123

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains an authenticated OS command injection vulnerability in /cgi-bin/dispatcher.cgi. The web_smtp_test_post handler incorporates a caller-supplied SMTP server value directly into a shell command without sanitization. A remote attacker with administrator web credentials can send a crafted SMTP server value to execute arbitrary operating-system commands on the device.
