Git for Windows has also been updated to include this Git LFS version.
#Smartgit sourcetree update#
According to the Git LFS maintainers, there is no workaround for this issue other than avoiding untrusted repositories.Īffected users and product vendors are advised to update to the latest Git LFS version (v2.12.1, released on Wednesday), which plugged the security hole. So its fine in a continuous Bash terminal, but given that SourceTree has. The vulnerability affects Git LFS versions 2.12 or earlier on Windows systems (but not on Unix). because theyve followed instructions from GitHub or SmartGit in the past. Golunski says that CVE-2020-27955 is trivial to exploit, and has released PoC exploit code, as well as video demonstrations of the exploit in action on various Git clients. The vulnerability can be triggered if the victim is tricked into cloning the attacker’s malicious repository using a vulnerable Git version control tool. As a result, the malicious git binary planted in this way will get executed instead of the original git binary located in a trusted path,” he explained. It gets great support from the repositories that are hosted by Bitbucket and GitHub. This organization has powered Jira and Bitbucket. This is a free Git client, which was developed by Atlassian. “As the exec.Command() implementation on Windows systems include the current directory, attackers may be able to plant a backdoor in a malicious repository by simply adding an executable file named: git.bat, git.exe, git.cmd or any other extension that is used on the victim’s system (PATHEXT environment dependent), in the main repo’s directory. SourceTree One of the interesting GUI Git clients is SourceTree.
Golunski found that Git LFS does not specify a full path to git binary when executing a new git process via a specific exec.Command() function. “Web applications / hosted repositories running on Windows which allow users to import their repositories from a URL may also be exposed to this vulnerability,” Golunski added.

– and likely other clients/development IDEs (i.e., those install git with the Git LFS extension by default). It can be exploited in a variety of popular Git clients in their default configuration – GitHub CLI, GitHub Desktop, SmartGit, SourceTree, GitKraken, Visual Studio Code, etc. A critical vulnerability (CVE-2020-27955) in Git Large File Storage (Git LFS), an open source Git extension for versioning large files, allows attackers to achieve remote code execution if the Windows-using victim is tricked into cloning the attacker’s malicious repository using a vulnerable Git version control tool, security researcher Dawid Golunski has discovered.
