CVE-2024-30270Public exploitNetwork attack vector

Arbitrary file overwrite via unchecked map paths

Published Apr 4, 2024 · Updated Dec 12, 2024

Path traversal in rspamd_maps() in mailcow: dockerized before 2024-04 allows remote authenticated users to overwrite server files. An invalid map name only triggers a loop continuation, so the unchecked value still forms a path opened for writing with attacker-controlled map content. Administrator access is required; writable-file permissions bound direct impact, although overwriting a suitable PHP file enables command execution inside the admin-panel container.
