Paid Memberships Pro <= 2.12.3 - Authenticated (Subscriber+) Arbitrary File Upload

7.5
Unrestricted Upload of File with Dangerous Type
CVE CVE-2023-6187
CVSS 7.5 (High)
Publicly Published November 16, 2023
Last Updated November 30, 2023
Researcher István Márton - Wordfence

Description

The Paid Memberships Pro plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'pmpro_paypalexpress_session_vars_for_user_fields' function in versions up to, and including, 2.12.3. This makes it possible for authenticated attackers with subscriber privileges or above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This can be exploited if 2Checkout (deprecated since version 2.6) or PayPal Express is set as the payment method and a custom user field is added that is only visible at profile, and not visible at checkout according to its settings.
