It is feasible that malware could be used to remotely fetch a memory dump from an infected system. This keeps the password out of the text box and it doesn’t end up in the system memory. A YubiKey is a USB stick which, when inserted into a USB slot of your computer, allows you to press the button and the YubiKey will enter the password for you.
There are a few things you can do if you’re worried about this vulnerability.
That being said, the gravity of the situation is different for people that are afraid their system might be confiscated and submitted to forensic analysis. However, there is no reason for most KeePass users to immediately panic and switch to a different password manager, because it would be very difficult for an attacker to get their hands on a memory dump of your system without you noticing. Unfortunately, a release for the new update (2.54) is not expected for a few months, since the developer is still working on a few other security related features. Since the developer has fixed the issue, this would normally be the place where we tell you to update KeePass. The issue was reported to the developer of KeePass on and relies on the way that Windows processes the input of a text box. In 2.54, there is different API usage and/or random string insertion for mitigation.” The memory dump can be a KeePass process dump, swap file (pagefile.sys), hibernation file (hiberfil.sys), or RAM dump of the entire system. The description of the vulnerability ( CVE-2023-32784) says: “In KeePass 2.x before 2.54, it is possible to recover the cleartext master password from a memory dump, even when a workspace is locked or no longer running.
However, a researcher has worked out a way to recover a master password, and has posted KeePass 2.X Master Password Dumper on GitHub. You absolutely do not want an attacker to get hold of your master password, since that is basically the key to your kingdom-aka “all your passwords are belong to us.” That encrypted database can only be opened with the master password. not only your passwords, but also your user names, URLs, notes, etc. In fact, KeePass encrypts the whole database, i.e. KeePass is a free open source password manager, which helps you to manage your passwords and stores them in encrypted form.
