WebNMS Framework Server Arbitrary File Upload



This module abuses a vulnerability in WebNMS Framework Server 5.2 that allows an unauthenticated user to upload text files by using a directory traversal attack on the FileUploadServlet servlet. A JSP file can be uploaded that then drops and executes a malicious payload, achieving code execution under the user which the WebNMS server is running. This module has been tested with WebNMS Framework Server 5.2 and 5.2 SP1 on Windows and 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/webnms_file_upload
msf exploit(webnms_file_upload) > show targets
msf exploit(webnms_file_upload) > set TARGET < target-id >
msf exploit(webnms_file_upload) > show options
    ...show and set options...
msf exploit(webnms_file_upload) > 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.
