CVE-2026-81945Network attack vector

Administrator-triggered service interruption via stack overflow

Published Sep 18, 2026 · Updated Sep 18, 2026

Stack overflow in the PLANET IGS-5225-8P2T4S web server allows remote authenticated users to interrupt service. The web server copies administrator-controlled request data into a stack buffer without sufficient bounds checking, allowing the buffer to overflow. Administrator-level access is required; exploitation can crash the service, while arbitrary code execution on the embedded operating system remains possible but unverified.
