CVE-2021-32965
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 prior to 1.1.0 are vulnerable to type confusion, which may 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 prior to 1.1.0 contains a type confusion vulnerability that can be exploited remotely. Type confusion occurs when the software fails to properly validate an object's type before using it, potentially allowing an attacker to manipulate memory and achieve arbitrary 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.
-
Identify if Delta Electronics DIAScreen is installedSearch the system for DIAScreen executables, installation directories, or check the list of installed programs. Common locations include Program Files directories or application-specific folders.Affected if DIAScreen is present on the system
-
Determine the installed DIAScreen versionRight-click the DIAScreen executable, select Properties, and view the Version tab. Alternatively, check any version information displayed within the application itself or in any installer logs.Affected if The version displayed is lower than 1.1.0 or no version is displayed (indicating an older release)
-
Confirm the version against the affected rangeCompare the identified version number to the vulnerable range: versions prior to 1.1.0. If the version cannot be determined or is ambiguous, treat it as potentially affected.Affected if The installed version is any release prior to 1.1.0, or the version cannot be verified
A system is affected if Delta Electronics DIAScreen is installed and the version is lower than 1.1.0.

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 · scoped1.1.0
Upgrade Delta Electronics DIAScreen to version 1.1.0 or later. In the interim, network segment affected systems and restrict external access to minimize exposure.
1.1.0
- Identify the currently installed version of DIAScreen
- Obtain DIAScreen version 1.1.0 or later from the official Delta Electronics vendor or authorized distributor
- Review the vendor's official upgrade documentation for DIAScreen
- Follow the documented upgrade procedure to update DIAScreen to version 1.1.0
- Verify the upgrade was successful by confirming the installed version is 1.1.0 or later
