Short explanation
The gix-fs library in gitoxide before version 0.24.1 can disclose NTLM credentials when a Windows user checks out a repository containing a crafted UNC symlink. The library calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.
Disclosed NTLM hashes can be used for pass‑the‑hash attacks, enabling attackers to impersonate users and access network resources.
What should be done?
- Upgrade gitoxide to version 0.24.1 or later
- Disable symlink support on Windows
- Monitor SMB authentication logs
- Follow vendor security advisory
- Implement network segmentation and access controls

Show the technical text from the sources
gix-fs in gitoxide before 0.24.1 contains a credential disclosure vulnerability that allows remote attackers to capture NTLM credentials by supplying UNC symlink targets in a crafted repository. When a victim checks out the repository on Windows with symlinks enabled, gix_fs::symlink::create calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.
