CVE-2023-0250
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 · uneditedDelta Electronics DIAScreen versions 1.2.1.23 and prior are vulnerable to a stack-based buffer overflow, which could allow an attacker to remotely 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 · moderate confidenceDelta Electronics DIAScreen versions 1.2.1.23 and prior contain a stack-based buffer overflow vulnerability that allows remote attackers to execute arbitrary code by overflowing a stack-allocated buffer, likely through crafted network input or file processing.

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 installation directorySearch for 'DIAScreen' or 'diascreen' in Program Files, Program Files (x86), or common Delta Electronics installation paths such as C:\Delta Electronics\DIAScreen or C:\Program Files\Delta\DIAScreenAffected if DIAScreen application is found on the system
-
Identify installed DIAScreen versionRight-click the DIAScreen executable (typically DIAScreen.exe), select Properties, and inspect the Version or File Version field. Alternatively, run 'wmic product where "name like '%DIAScreen%'" get version,name' or check Add/Remove Programs for the version entryAffected if Version is 1.2.1.23 or prior
-
Determine if DIAScreen network services are activeOpen Command Prompt and run 'netstat -ano | findstr LISTENING' to list listening ports, then cross-reference with any ports DIAScreen is known to use (consult application documentation or check for delta/dia-related listening services in Services.msc)Affected if DIAScreen is running as a network service listening on open ports
-
Check for recent DIAScreen file processingReview Windows Event Viewer under Security or Application logs for entries related to DIAScreen file operations, or inspect the application's recent files/documents if a GUI is availableAffected if DIAScreen is configured to process files from untrusted network sources or external inputs
The system is affected if DIAScreen version 1.2.1.23 or prior is installed and the application is running or accessible to process network or file input.

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 DIAScreen to a patched version newer than 1.2.1.23. If patching is immediately infeasible, network-segment the affected system and restrict external access to reduce the remote attack surface.
