Syncthing · Syncthing · CVE-2017-1000420
**Name of the Vulnerable Software and Affected Versions**
Syncthing versions 0.14.33 and older
**Description**
The issue allows for symlink traversal, resulting in arbitrary file overwrite. This occurs because Syncthing erroneously versions symlinks when they are deleted. If a directory is then created with the same name, a file created in that directory, and the file deleted, it is moved into the symlink target.
**Recommendations**
For Syncthing versions 0.14.33 and older, update to a version newer than 0.14.33 to resolve the issue. As a temporary workaround, consider restricting the creation of symlinks and directories with the same name to minimize the risk of exploitation.
