MDJM Event Management <= 1.7.8.3 - Authenticated (Administrator+) Arbitrary File Upload via 'mdjm_email_upload_file' Parameter
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The MDJM Event Management plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7.8.3 via the mdjm_send_comm_email function. This is due to no file type, extension, or MIME type validation being performed on uploaded files. This makes it possible for authenticated attackers, with administrator-level access and above, to upload files that may be executable, which makes remote code execution possible.
