high Tenable OT Security Plugin ID 506479

Synopsis

The remote OT asset is affected by a vulnerability.

Description

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote administrator to cause a denial of service or potentially execute arbitrary code on the underlying operating system.
