CVE-2019-1353Network attack vector

Code execution via unprotected NTFS path aliases

Published Jan 24, 2020 · Updated Aug 4, 2024

Code execution in affected Microsoft Git releases allows remote attackers to run code during a clone from a crafted repository. The path validator leaves core.protectNTFS disabled outside native Windows, so NTFS short names such as git~1 or alternate data streams can alias protected .git paths. Exploitation requires cloning an untrusted repository in WSL on a Windows drive with short names enabled, or on macOS through an SMB share; code runs with the cloning user's privileges.
