CVE-2023-43817
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 · uneditedA buffer overflow exists in Delta Electronics Delta Industrial Automation DOPSoft version 2 when parsing the wMailContentLen field of a DPS file. An anonymous attacker can exploit this vulnerability by enticing a user to open a specially crafted DPS file to achieve 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 confidenceA buffer overflow vulnerability exists in Delta Electronics DOPSoft version 2 when parsing the wMailContentLen field within DPS files. By crafting a DPS file with an oversized wMailContentLen value, an attacker can overwrite memory and achieve arbitrary code execution when a user opens the malicious file.

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.
-
Verify DOPSoft installationCheck for Delta Electronics DOPSoft installation in Program Files, Program Files (x86), or the application's typical installation directory. Look for executable files named DOPSoft.exe or similar.Affected if DOPSoft version 2.x is installed on the system
-
Determine installed DOPSoft versionRight-click the DOPSoft executable, select Properties, and check the Version tab for the File Version. Alternatively, launch DOPSoft and look for version information in the Help or About menu.Affected if The installed version is 2.00.00.00, 2.00.07.04, or any version between these (e.g., 2.00.01.00, 2.00.05.02)
-
Confirm DPS file parsing is usedDetermine if the system or user workflow involves opening .DPS project files. The vulnerability triggers when DOPSoft parses DPS files containing the wMailContentLen field.Affected if Users open DPS files created by or obtained from untrusted sources
If DOPSoft version 2.00.00.00 through 2.00.07.04 is installed and users open DPS files from untrusted sources, the environment is vulnerable to this buffer overflow.

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 DPS files from untrusted sources until an official vendor patch is available. Organizations should implement file vetting controls and monitor for the release of security updates from Delta Electronics.
