CVE-2026-81942Network attack vector

Root command execution via unfiltered system input

Published Sep 18, 2026 · Updated Sep 18, 2026

OS command injection in PLANET IGS-5225-8P2T4S V1/V2 before 1.2412b260707 and 2.2412b260519 allows remote authenticated users to gain root access. The web server passes user-supplied input to system() without sufficient filtering, so shell metacharacters reach the underlying operating system. Access to the authenticated management interface is required; successful exploitation executes arbitrary commands as root.
