Short explanation

Rclone before 1.75.2 contains a path traversal vulnerability in serve webdav that allows unauthenticated attackers to write above the served root by sending an unvalidated '..' path component. Attackers can send MKCOL /.. to plant a VFS node, then PUT, MOVE, COPY, or MKCOL to create, overwrite, or delete files belonging to other tenants.

Why does it matter?

This vulnerability matters because unauthenticated attackers can remotely compromise file integrity and manipulate data belonging to other tenants.

What should be done?

  • Follow vendor advisories
  • Update the affected rclone version
  • Restrict WebDAV service access
