CVE-2026-81943

Estado: AplazadaAlta (8.4)—

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain active debug functionality in the embedded software. An attacker with privileged access to the device can enable this debug mode to execute arbitrary code on the underlying operating system and gain root-level access.
