Purpose

The purpose of this document is to outline the issues surrounding FileZilla updates particularly related to the downloading of the patch files from the vendor.

Cause

Changes from the vendor, Filezilla, has caused downloads of the updates not from a Web browser to fail with an error 403 authentication error. From review, the cause is the lack of user token authentication as updates downloaded through Patch for Windows are done on behalf of a user or system account, not as the actual user. Additional findings have shown the direct download links to also reroute to the main Filezilla site versus downloading the actual installer.

Resolution

The current workaround to this issue can be found in this document: How To: Supply and Deploy Patches That Can Not Be Downloaded
