CODESYS Runtime: Unrestricted File Download via CmpApp (CVE-2023-37551)
CVE-2023-37551 6.5 - Medium - August 03, 2023

In multiple Codesys products in multiple versions, after successful authentication as a user, specially crafted network communication requests can utilize the CmpApp component to download files with any file extensions to the controller.
