A Remote code execution vulnerability exists in DEXT5Upload in DEXT5 through 2.7.1402870. An attacker can upload a PHP file via dext5handler.jsp handler because the uploaded file is stored under dext5uploadeddata/.

handler/upload_handler.jsp in DEXT5 Editor through 3.5.1402961 allows an attacker to download arbitrary files via the savefilepath field.

DEXT5Upload 2.7.1262310 and earlier is affected by Directory Traversal in handler/dext5handler.jsp. This could allow remote files to be downloaded via a dext5CMD=downloadRequest action with traversal in the fileVirtualPath parameter (the attacker must provide the correct fileOrgName value).

A vulnerability (improper input validation) in the DEXT5 Upload solution allows an unauthenticated attacker to download and execute an arbitrary file via AddUploadFile, SetSelectItem, DoOpenFile function.(CVE-2020-7832)

Parameter manipulation can bypass authentication to cause file upload and execution. This will execute the remote code. This issue affects: Raonwiz DEXT5Editor versions prior to 3.5.1405747.1100.03.

DEXT5 Upload 5.0.0.117 and earlier versions contain a vulnerability, which could allow remote attacker to download and execute remote file by setting the argument, variable in the activeX module. This can be leveraged for code execution.
