CVE-2020-25186
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 · uneditedAn XXE vulnerability exists within LeviStudioU Release Build 2019-09-21 and prior when processing parameter entities, which may allow file disclosure.
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 confidenceAn XML External Entity (XXE) vulnerability exists in LeviStudioU Release Build 2019-09-21 and prior versions. The vulnerability is triggered when processing XML parameter entities, allowing an attacker to potentially read arbitrary files from the server through malicious XML input.

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 LeviStudioU is installedCheck for LeviStudioU in installed programs (Windows: Control Panel > Programs and Features, or search for LeviStudioU in start menu)Affected if LeviStudioU is present on the system
-
Determine the installed versionRight-click the LeviStudioU executable, select Properties, then go to the Details tab to view the version number or build dateAffected if Version/build date is 2019-09-21 or earlier
-
Locate the application executable pathFind the LeviStudioU.exe file location (commonly in C:\Program Files\ or C:\Program Files (x86)\ or a project-specific directory)Affected if The executable exists and the version check in step 2 shows an affected build
-
Identify XML input usageReview project files, configuration files, or documentation that reference XML processing within LeviStudioU workflowsAffected if The application processes XML files as part of its normal operation
You are affected if LeviStudioU is installed with Release Build 2019-09-21 or earlier AND the application processes XML input, enabling the XXE vulnerability.

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 to a patched version of LeviStudioU if available. If no patch exists, disable external entity processing in the XML parser or implement input validation to reject malicious XML payloads.
