CVE-2019-19169

Code execution via attacker-controlled ActiveX download arguments

Published May 6, 2020 · Updated Aug 5, 2024

Arbitrary file download in RAONWIZ DEXT5 Upload 5.0.0.116 and earlier allows remote attackers to execute code through Dext5.ocx. The Dext5.ocx control accepts attacker-set arguments for an unnamed ActiveX method and uses them to download an arbitrary file. Exploitation requires a Windows user to interact with content that invokes the installed control, after which the downloaded file can be used for code execution.
