Summary
Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) vulnerability in ash-project ash_admin allows writing attacker-controlled bytes to arbitrary paths on the server.
AshAdmin.Components.Resource.Form.consume_file_uploads/1builds the destination asPath.join([tmp_dir, entry.client_name])and writes it withFile.cp!/2.entry.client_nameis the browser-supplied filename and is not sanitized, andPath.join/1does not normalize... An upload named../../../../var/www/app/priv/static/x.pngtherefore escapes the random temp directory and lands anywhere the BEAM user can write, enabling arbitrary file write and potentially remote code execution by overwriting application assets, configuration, or cron/ssh files. The only guard is an extension allowlist defaulting to:anythat checks only the extension. The fix strips path components withPath.basename/1before joining.This issue affects ash_admin: from 0.13.7 before 1.3.1.
