CVE-2020-7875Network attack vector

Code execution via unvalidated ActiveX file download

Published Oct 28, 2021 · Updated Aug 4, 2024

Code execution in the ActiveX module in RAONWIZ DEXT5 Upload 5.0.0.117 and earlier allows remote attackers to run remote files. The ActiveX module accepts an attacker-controlled method argument, downloads the referenced file, and executes it without validating its origin or integrity. Exploitation requires a Windows user to interact with content that invokes the installed Internet Explorer plug-in, after which the file runs with that user's privileges.
