| CVE-2026-71283 | 1 Fledge-iot | 1 Fledge | 2026-08-07 | 4.9 Medium |
| Fledge's backup-restore upload handler, upload_backup() (python/fledge/services/core/api/backup_restore.py), calls tarfile.extractall(temp_path) on an admin-uploaded tar archive with no filter argument and no per-member path validation. A crafted tar archive containing member names with `../` path components extracts files outside the intended temporary directory, allowing arbitrary file writes anywhere on the filesystem reachable by the Fledge process. Requires the admin role (@has_permission("admin")). | ||||
| CVE-2026-71284 | 1 Fledge-iot | 1 Fledge | 2026-08-07 | 7.2 High |
| Fledge's backup-restore upload handler, upload_backup() (python/fledge/services/core/api/backup_restore.py), takes the first extracted tar member's filename (tar_file_names[0]) and builds a shell command via string formatting: `cmd = "cp {} {}".format(source, backup_path); ret_code = os.system(cmd)`. The only pre-check on the filename is a prefix/suffix match (startswith(backup_prefix), endswith(valid_extensions)), which a name such as `fledge_backup_$(id>/tmp/pwn).db` satisfies while still injecting a shell command substitution. Because os.system() invokes a shell and no quoting (shlex.quote, list-form subprocess) is applied, an admin uploading a crafted backup archive achieves arbitrary OS command execution. | ||||
