| !!REGARDING 10.5.6 and the recent global SSH vulnerability which also affected CrushFTP! (not CrushFTP specific, but we are affected just like most other server vendors) |

| !!!__Update Bug on Windows__ |
| Some versions of CrushFTP had a problem applying an update automatically. They would fail to rename ".jar" files on Windows operating systems. They would instead leave behind ".jar_tmp" files needing the "_tmp" manually removed from them. This has been fixed for a while, but if you are still on one of these older builds, you will be affected the next time you attempt the update. So you need to fix the jar filenames one time manually. Example: CrushFTP.jar_tmp -> CrushFTP.jar. Same for all other jars in plugins, plugins/lib folder, and the WebInterface folder has CrushTunnel.jar. Do all 3 locations entirely. |

| !!REGARDING THE RECENT VULNERABILITY ANNOUNCEMENT NOVEMBER 16, 2023! |
| If your CrushFTP is lower than 10.5.5, you are vulnerable to an exploit that was responsibly disclosed. It is not known to be in he wild, but its severe and everyone must update immediately. All versions of CrushFTP...v4/v5/v6/v7/v8/v9/v10 were affected by this. CrushFTP v11 is not affected by this as it has been patched before its first public release. One part of the vulnerability allows an attacker to gain access simply by knowing the admin username, and the other parts when used together allows an attacker who has a non privileged account to gain access to files outside their VFS which can then be in turn used to login as a more privileged user. CVE release is pending. Credit goes to the UK NCSC.\\ |

| !!Vulnerability Info |
| __November 11th, 2024 - (CVE - coming soon...pending)\\ |
| V10 versions below 10.8.3 and V11 versions below 11.2.3 are vulnerable to a password reset email exploit. If an end user clicks the link, their account is compromised. |
| (CREDIT: Stratascale Cyber Research Unit)__\\ |
| Once you update you must configure your allowed email reset URL domains.\\ |
| v10:Preferences, WebInterface, MiniURL: Set an allowed list of domains, comma separated.\\ |
| v11:Preferneces, WebInterface, Login Page: Set a domain pattern that is not just '*' as a '*' is no longer allowed.\\ |

| 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 vulnerable.\\ |
| This vulnerability is critical because it does NOT require any authentication. It can be done anonymously and steal the session of other users and escalate to an administrator user. Its critical everyone updates ASAP! 10.5.2 changes other defaults related to loading DB drivers that are not in your classpath has also changed. This means if your DB drivers are not part of your plugins/lib folder, they will not be loaded by CrushFTP. (Statistics DB if you changed it, SQL Users if you are using that, etc.)\\ |
| !!FAQ: |
| •If I'm on v10.8.3+...do I need to upgrade to v11? No, 10.8.3+ are safe.\\ |
| •If I'm on v10.6.1, or v10.3, or v10.5.5, am I vulnerable? Yes! Update immediately to 10.8.3+ or v11.2.3+.\\ |

| __IMPORTANT: due to the security updates since CrushFTP version 10.5.2+ any JDBC driver jar file needs to be placed into the CrushFTP10/plugins/lib/ directory, or it won't load. In case of a server previously configured using an external SQL user DB, this new feature prevents access on next launch, will need to move the jar file, then edit prefs.XML, update the <db_driver> key value like\\ |
