CVE-2018-17927
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 · uneditedIn Delta Industrial Automation TPEditor, TPEditor Versions 1.90 and prior, multiple out-of-bounds write vulnerabilities may be exploited by processing specially crafted project files lacking user input validation, which may cause the system to write outside the intended buffer area and may allow remote code execution.
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 confidenceDelta Industrial Automation TPEditor versions 1.90 and prior contain multiple out-of-bounds write vulnerabilities in project file parsing. The application fails to validate input when processing specially crafted project files, allowing attackers to write beyond allocated buffer boundaries. This memory corruption can potentially be leveraged for remote code execution.

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.
-
Confirm TPEditor is installedOpen Control Panel > Programs and Features, or run 'wmic product get name,version' and look for 'TPEditor' or 'Delta TPEditor'Affected if TPEditor appears in the installed programs list
-
Identify installed TPEditor versionRight-click the TPEditor executable (typically in C:\Program Files\Delta Industrial Automation\TPEditor or similar), select Properties, then view the Details tab for the version numberAffected if Version displayed is 1.90 or lower
-
Check version via command lineRun 'reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" /s | findstr /i "TPEditor"' to locate the registry entry, then check the Version valueAffected if Registry shows version <= 1.90 or no version entry exists alongside TPEditor installation
-
Determine if project file handling is in useCheck if the TPEditor application is used to open or edit .tp project files - look for recent .tp files in Documents or project directoriesAffected if The application is used to open, create, or edit TPEditor project files (.tp extension)
-
Verify file parsing vulnerability trigger pointThe vulnerability triggers when TPEditor parses a specially crafted project file - no special configuration needed; the flaw exists in the parsing routines themselvesAffected if TPEditor <= 1.90 is installed and can process project files
The environment is affected if Delta Industrial Automation TPEditor version 1.90 or lower is installed, as the out-of-bounds write vulnerabilities exist in the project file parsing code regardless of configuration.

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 project files from untrusted sources. The vendor should implement proper input validation and bounds checking in all project file parsing routines, and distribute a patched version with corrected buffer handling.
