Description

This module exploits a vulnerability found in ClipBucket versions before 4.0.0 (Release 4902). A malicious file can be uploaded using an unauthenticated arbitrary file upload vulnerability. It is possible for an attacker to upload a malicious script to issue operating system commands. This issue is caused by improper session handling in /action/beats_uploader.php file. This module was tested on ClipBucket before 4.0.0 - Release 4902 on Windows 7 and Kali Linux.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/multi/http/clipbucket_fileupload_exec
msf exploit(clipbucket_fileupload_exec) > show targets
    ...targets...
msf exploit(clipbucket_fileupload_exec) > set TARGET < target-id >
msf exploit(clipbucket_fileupload_exec) > show options
    ...show and set options...
msf exploit(clipbucket_fileupload_exec) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
