CVE-2024-11789
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFuji Electric Monitouch V-SFT V10 File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Monitouch V-SFT. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of V10 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24448.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStack-based buffer overflow in Fuji Electric Monitouch V-SFT V10 file parser. The vulnerability results from insufficient validation of user-supplied data length before copying to a stack-based buffer during V10 file parsing, allowing arbitrary code execution in the current process context.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Monitouch V-SFT versionLocate the Monitouch V-SFT installation directory and check the file version information. This is typically found in the program's properties or by running 'powershell Get-ItemProperty' on the main executable (commonly named V-SFT.exe or similar in the installation folder).Affected if The installed version is exactly 6.2.3.0
-
Identify if V10 file parsing is in useDetermine whether the Monitouch V-SFT software is configured to import, open, or parse V10 project files. Check recent file access logs or monitor the process when users open .v10 files.Affected if V10 file parsing feature is actively used or configured on the system
-
Review recent V10 file accessExamine file access logs, recent documents, or the application's recent files list for any .v10 files that have been opened. Check the application's file open history if available.Affected if Any V10 files have been opened from untrusted or unknown sources
-
Check for indicators of compromiseReview any available HMI or engineering workstation logs for unusual behavior, unexpected process spawns, or crash dumps related to the V-SFT application around the time of V10 file processing.Affected if Unusual logs, crashes, or unexpected process behavior are present after V10 file handling
A system is affected if Monitouch V-SFT version 6.2.3.0 is installed AND the V10 file parser feature is being used to process files, particularly from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUsers should avoid opening untrusted V10 files and only use files from trusted sources. Organizations should monitor for vendor patches from Fuji Electric and apply them when available. Network segmentation can limit exposure for industrial environments.
