|
|
This module exploits a vulnerability found in Western Digital Arkeia Appliance
|
|
version 10.0.10 and lower. By abusing the upload.php script,
|
|
a malicious user can upload arbitrary code to the ApplianceUpdate file in the temp
|
|
directory without authentication. Abusing the local file inclusion in the lang
|
|
cookie to parse this file results in arbitrary code execution, also without
|
|
authentication. The module has been tested successfully on Arkeia 10.0.10. The issues
|
|
have been fixed in version 10.1.10.
