CVE-2025-7231
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 · uneditedINVT VT-Designer PM3 File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of INVT VT-Designer. 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 PM3 files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25724.
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 confidenceThis is an out-of-bounds write vulnerability in INVT VT-Designer's PM3 file parser. The lack of proper validation of user-supplied data during PM3 file parsing allows writing past the end of an allocated buffer, which can be leveraged to achieve 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 if INVT VT-Designer is installedLook for VT-Designer in the installed programs list (Windows: Control Panel > Programs and Features, Linux: check /opt or /usr/local directories, or use 'dpkg -l' / 'rpm -qa')Affected if VT-Designer software is present on the system
-
Determine the installed VT-Designer versionOpen VT-Designer, go to Help > About, or check the program's file properties (right-click executable > Properties > Details). On Windows, also check the uninstall registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Affected if The version is exactly 2.1.13
-
Verify PM3 file support is presentCheck if the PM3 file parser module exists in the VT-Designer installation directory. Look for files with .pm3 extension support or PM3-related DLLs/plugins in the program folderAffected if PM3 parsing functionality is included in the installation
-
Check for recent PM3 file usageReview recent file open dialog history, recent documents, or check the application log for PM3 file operationsAffected if PM3 files have been opened in this installation
If INVT VT-Designer version 2.1.13 is installed and PM3 file parsing functionality is present, the environment is affected by this vulnerability.

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 PM3 files from untrusted sources. The vendor should implement proper bounds checking and input validation in the PM3 file parsing logic to prevent out-of-bounds writes.
