Summary
[none]
Details

In Git for Windows, the Windows port of Git, no localized messages are shipped with the installer. As a consequence, Git is expected not to localize messages at all, and skips the gettext initialization. However, due to a change in MINGW-packages, the gettext() function's implicit initialization no longer uses the runtime prefix but uses the hard-coded path C:\mingw64\share\locale to look for localized messages. And since any authenticated user has the permission to create folders in C:\ (and since C:\mingw64 does not typically exist), it is possible for low-privilege users to place fake messages in that location where git.exe will pick them up in version 2.40.1. This vulnerability is relatively hard to exploit and requires social engineering. For example, a legitimate message at the end of a clone could be maliciously modified to ask the user to direct their web browser to a malicious website, and the user might think that the message comes from Git and is legitimate. It does require local write access by the attacker, though, which makes this attack vector less likely. Version 2.40.1 contains a patch for this issue. Some workarounds are available. Do not work on a Windows machine with shared accounts, or alternatively create a C:\mingw64 folder and leave it empty. Users who have administrative rights may remove the permission to create folders in C:\.
