Reichl described the flaw in a security report released on GitHub on Thursday, exactly where he also clarified the vulnerability could be exploited only if the learn password is typed on a keyboard and not if it is copied from the clipboard.
The flaw in KeePass involves a textual content box referred to as SecureTextBoxEx made use of for password entry. It makes leftover strings in memory when characters are typed, generating them tough to get rid of because of to .NET’s habits.
For instance, when typing “Password,” residual strings like •a, ••s, •••s, ••••w, •••••o, ••••••r, •••••••d are saved in memory. A evidence-of-idea (POC) software formulated by Reichl was ready to scan the memory dump, suggesting very likely password characters for every place.
Additionally, the attack demands no code execution on the concentrate on technique, only a memory dump. The memory can be sourced from many documents, like a RAM dump of the entire method. The flaw can also bypass the workspace’s locked standing, as the password can be extracted from the memory even right after KeePass is no extended working (even though the prospects minimize above time).

To mitigate the risk affiliated with this vulnerability, buyers are suggested to update to KeePass 2.54 or a increased version when it results in being available.
In the meantime, Reichl suggested KeePass consumers adjust their grasp password, restart their computer, delete the hibernation file and pagefile/swapfile, and overwrite deleted knowledge on the challenging disk travel (HDD) to avert details carving.
Accomplishing a fresh set up of the working process (OS) is also advised to be certain optimum security.
The developer also clarified that some KeePass-dependent products, these types of as KeePassXC, Strongbox and KeePass 1.X, are not impacted by the vulnerability.
The security report will come months after the LastPass breaches introduced password supervisors into the highlight.
