![]() ![]() It also provides access to process memory space, including a neat string search feature. Process Hacker allows users to inspect every process that is currently running on their system. ![]() To locate a known master password in memory, one can use a tool like Process Hacker. I then moved onto the Bitwarden Desktop App, where the issue is still present. However, after an update in either Chrome and/or Bitwarden fixed the issue, so I was no longer able to identify the password in memory. I started off by focusing on the Bitwarden web browser extension (both for Chrome and MSEdge), where a initial proof of concept was developed. Some of the tests involved checking whether master passwords are leaked before and after locking, and as a user myself I was curious, so I tried the tests myself. This issue references an article by a German IT magazine who had tested different password managers. BackgroundĪ few years ago, a GitHub issue relating to the Bitwarden client application ( Erase Master Password in memory after login) was reported. Bitwarden Desktop version 2023.7.0 and below are vulnerable. Update (): A patch was released on GitHub ( 5813) which fixes the vulnerability. Update (): This particular issue has been assigned CVE-2023-38840 There should have been a video here but your browser does not seem The video belows shows a quick demo (getting the master password from the Bitwarden web browser extension) It was tested with Bitwarden desktop app version (2023.2.0). We developed a proof of concept tool, called BW-dump, that works on Windows platforms. It is possible to identify unknown Bitwarden master passwords in memory, even after a vault is locked. I also cover the decisions made for developing a proof of concept to automate the process of extracting potential passwords. In default, it check unique key(data duplicated) and you can define custom validate logics.A blog post on how I was able to identify unknown master passwords stored in the memory of the Bitwarden web extension and desktop client, after a vault has been locked. You can validate data by MemoryDatabase.Validate method. var builder = new DatabaseBuilder ( ) īuilder. to create database, use DatabaseBuilder and Append method. Prepare the example table definition like following. Install the core library(Runtime and Annotations). NET Core(for Unity is in below sections). Runtime library API is the same but how to code-generate has different way between. MasterMemory uses C# to C# code-generator. PalDB developed by LinkedIn has a similar concept(embeddable write-once key-value store), but the implementation and performance characteristics are completely different. MasterMemory has better performance than any other database solutions. These features are suitable for master data management(write-once, read-heavy) on embedded application such as role-playing game. Metadata, To make custom importer/exporter, get the all database metadata.Validator, You can define custom data validation by C#.Flexible Search, Supports multiple key, multiple result, range/closest query.Fast load speed, MasterMemory save data by MessagePack for C#, a fastest C# serializer so load speed is blazing fast.TypeSafe, 100% Type safe by pre code-generation.Performance, Similar as dictionary lookup.Memory Efficient, Only use underlying data memory and do aggressively string interning.When SQLite is 3560kb then MasterMemory is only 222kb. NET Core and Unity.Ĥ700 times faster than SQLite and achieves zero allocation per query. Embedded Typed Readonly In-Memory Document Database for. ![]()
