CVE-2024-7502
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 crafted DPA file could force Delta Electronics DIAScreen to overflow a stack-based buffer, which could allow an attacker to execute arbitrary code.
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 Electronics DIAScreen contains a stack-based buffer overflow vulnerability when parsing specially crafted DPA files. The application fails to properly validate the size of input data before copying it into a fixed-size stack buffer, allowing an attacker to overwrite stack frames and achieve arbitrary code execution with the application's privileges.

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.
-
Locate DIAScreen installationSearch for 'DIAScreen' or 'Diascreen' in Program Files directories, or check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Delta Electronics software entriesAffected if DIAScreen is found installed on the system
-
Determine installed versionRight-click the DIAScreen executable (typically named DIAScreen.exe) and select Properties, then check the Details tab for File Version; alternatively, launch DIAScreen and navigate to Help > AboutAffected if The displayed version is lower than 1.4.2 (for example, 1.4.1, 1.4.0, or earlier)
-
Verify DPA file parsing capability existsCheck if DIAScreen can open or import DPA files by looking for File > Open, File > Import, or similar menu options that reference .dpa file extensionsAffected if DPA file parsing functionality is present and accessible in the application
-
Examine crash logs or event logs for DPA-related failuresOpen Windows Event Viewer and check Application logs for faulting module DIAScreen.exe around the time of opening DPA files, or check for .dmp crash dump files in DIAScreen's log or temp directoriesAffected if Recent crash events or dumps exist related to DPA file processing
A system is affected if DIAScreen version is installed and is lower than 1.4.2, and the application has the ability to parse DPA files.

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.
dbcve · scoped1.4.2
Implement proper bounds checking on all DPA file parsing routines to validate input sizes before buffer operations. Users should avoid opening DPA files from untrusted sources until a vendor patch is available.
1.4.2
- Check the current installed version of Delta Electronics DIAScreen
- Obtain DIAScreen version 1.4.2 or later from the official Delta Electronics website or authorized distribution channels
- Back up any existing DIAScreen configurations, settings, or project files before upgrading
- Install the updated DIAScreen version 1.4.2 or later following standard installation procedures
- Verify the installation was successful by checking the updated version number
- Test that DIAScreen functions normally with legitimate DPA files
