CVE-2018-7507
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 · uneditedWPLSoft in Delta Electronics versions 2.45.0 and prior utilizes a fixed length heap buffer where a value larger than the buffer can be read from a file into the buffer, causing the buffer to be overwritten, which may allow remote code execution or cause the application to crash.
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 · moderate confidenceWPLSoft (Delta Electronics PLC programming software) versions 2.45.0 and prior contain a heap-based buffer overflow vulnerability. The application uses a fixed-size heap buffer when reading data from files, but fails to validate that the input data size does not exceed the buffer capacity before copying. This allows an attacker to overflow the heap buffer by supplying a specially crafted file containing data larger than the allocated buffer, potentially achieving remote code execution or causing denial of service.

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 WPLSoft installationSearch for WPLSoft on the system by checking Program Files directories or using system inventory tools. Look for the WPLSoft.exe executable.Affected if WPLSoft is present on the system
-
Determine installed WPLSoft versionLocate the WPLSoft executable and retrieve its version information. Right-click on the executable, select Properties, then view the Details tab for version number, or use command-line tools to query the file version.Affected if Cannot retrieve version information or version is <= 2.45.0
-
Compare version against affected rangeCompare the installed version number to the affected range. Versions 2.45.0 and prior are within the affected range.Affected if Installed version is 2.45.0 or lower (for example, 2.44.0, 2.40.0, etc.)
-
Assess file processing exposureDetermine if WPLSoft is used to open project files from external or untrusted sources. The vulnerability is triggerable through malicious file parsing when the application reads specially crafted files.Affected if WPLSoft is used to process project files from untrusted or external sources
The environment is affected if WPLSoft version 2.45.0 or lower is installed and the application is used to open project files, since the heap-based buffer overflow can be triggered during file parsing.

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 dataUpgrade WPLSoft to a version newer than 2.45.0. Until the upgrade is available, exercise caution when opening WPLSoft project files from untrusted sources, as the vulnerability is triggerable through malicious file parsing.
