| !!REGARDING THE RECENT VULNERABILITY ANNOUNCEMENT AUGUST 10, 2023! |
| __April 19th, 2024 - CVE-2024-4040\\ |
| CrushFTP v11 versions below 11.1 have a vulnerability where users can escape their VFS and download system files. This has been patched in v11.1.0. Customers using a [DMZ] in front of their main CrushFTP instance are partially protected with its protocol translation system it utilizes. A DMZ however does not fully protect you and you must update immediately. (CREDIT:Simon Garrelou, of Airbus CERT)__\\ |

| If your CrushFTP version is less then 10.5.1, you are vulnerable. No exception. Look at your version number on the dashboard, and it must be 10.5.1 or higher to be safe. For reference, v6, v7, v8,v9...those numbers are less than v10.5.1. Yes, they are vulnerable! Anything below 10.5.1 is vulenrable.\\ |
| !!FAQ: |
| •If I'm on v10.7.1...do I need to upgrade to v11? No, just update v10 to v10.7.1.\\ |
| •If I'm on v10.6.1, or v10.3, or v10.5.5, am I vulnerable? Yes! Update immediately to 10.7.1.\\ |
| •Can you tell me how I can check if I have been exploited? Not really..the nature of this was common words that could be in your log already. So there is no silver bullet search term to check for. Looking for "<INCLUDE" is an indicator.\\ |
| •If I have a DMZ am I safe? NO! As of April 22, we have changed our opinion on this. A DMZ does not fully protect you.\\ |
| •If I only have my SFTP port exposed to the internet but not any web ports...am I safe? Yes, this exploit specifically works with the WebInterface port.\\ |
