|
|
This module exploits a file upload vulnerability found in XODA 0.4.5. Attackers
|
|
can abuse the "upload" command in order to upload a malicious PHP file without any
|
|
authentication, which results in arbitrary code execution. The module has been
|
|
tested successfully on XODA 0.4.5 and Ubuntu 10.04.
