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 confidenceRAONWIZ RAON KUpload component lacks proper file extension validation, allowing remote attackers to upload and execute arbitrary files. This file download and execution vulnerability enables remote code execution by bypassing extension checks.

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 RAONWIZ RAON K Upload is installedSearch for RAON K Upload components, DLLs, or web application modules in the application directory or web server. Look for files named 'KUpload' or related RAONWIZ components.Affected if RAONWIZ RAON K Upload component files are found in the environment
-
Determine the installed versionCheck the version information of the KUpload component (file properties, assembly info, or version metadata). Compare the version number to the affected range: versions before 2018.0.2.51.Affected if The installed version is lower than 2018.0.2.51
-
Verify the upload functionality is exposedCheck if the KUpload file upload handler or endpoint is accessible on the web server. Look for upload-related URLs, servlets, or API endpoints associated with the component.Affected if The upload functionality is accessible and accepts file uploads
-
Test for extension validation bypassAttempt to upload a file with a non-image executable extension (such as .asp, .aspx, .jsp, .php, or .exe) through the KUpload component and verify if the file is accepted or if extension validation rejects it.Affected if Files with executable extensions are accepted or stored by the upload component without proper validation
The environment is affected if RAONWIZ RAON K Upload version below 2018.0.2.51 is installed and its upload functionality is accessible without proper extension validation in place.
