CVE-2022-28052Public exploitNetwork attack vector

Authenticated arbitrary file write via path traversal

Published Apr 13, 2022 · Updated Aug 3, 2024

Path traversal in Roothub 2.6.0 allows remote authenticated users to write uploaded files outside the configured storage directory. The /common/upload handler passes customPath to FileSystemStorageService.store, which concatenates it with the upload directory without canonicalization or a containment check. A low-privileged account can place files at attacker-selected paths; code execution in the demonstrated payload requires a later victim shell login.
