Fuji Electric Smart Editor arbitrary code execution flaws
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
Three memory-corruption flaws in Smart Editor v1.0.1.0 and prior allow arbitrary code execution; update to v1.0.2.0.
Fuji Electric Smart Editor versions 1.0.1.0 and prior contain three separate memory-corruption vulnerabilities—an out-of-bounds read (CVE-2025-32412), out-of-bounds write (CVE-2025-41413), and stack-based buffer overflow (CVE-2025-41388)—each with CVSS v4 score 8.4. All three require local attack surface and user interaction but grant full code execution capability if exploited. The vulnerabilities affect critical manufacturing environments worldwide; CISA reports no active exploitation in the wild at publication. Mitigation is straightforward: update to Smart Editor v1.0.2.0 or later. Organizations should apply network segmentation to isolate engineering workstations running Smart Editor from direct internet exposure and restrict access via VPN where remote engineering is necessary.

Detection guidance
Fuji Electric Smart Editor Spawning Command Interpreter or Script Host
Smart Editor spawning a shell, script host or LOLBin child process, which is possible post-exploitation behaviour after memory-corruption code execution (CVE-2025-32412, CVE-2025-41413, CVE-2025-41388). Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
title: Fuji Electric Smart Editor Spawning Command Interpreter or Script Host
description: Detects a process whose parent image path contains Smart Editor (Fuji
Electric) launching a command interpreter, script host or common LOLBin. Editor
applications rarely spawn these, so a hit may indicate successful exploitation of
a memory-corruption flaw via a crafted project file. The parent image name is matched
by substring because the exact binary name is not given in the advisory; tune it
to your installed binary.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,853 reports from 146 sources, 616 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
