CVE-2021-32814Public exploitNetwork attack vector

Host file destruction via MKSNAP path traversal

Published Aug 3, 2021 · Updated Aug 3, 2024

Path traversal in Skytable before 0.5.1 allows remote authenticated users to delete or overwrite host files through MKSNAP. The enhanced MKSNAP action accepts its second argument as a snapshot name and resolves ../ sequences outside the snapshot directory before writing the .snapshot path. A connected client can damage only files writable by the database-server process, but the result can corrupt application or host data.
