At a glance

CVE-2023-50855 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Pre* Party Resource Hints WordPress plugin, affecting versions < 1.8.19. It carries a CVSS score of 6.6 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 1.8.19; sites on affected versions should update now. Disclosed December 2023, reported by Muhammad Daffa.

Vulnerability Overview

The Pre* Party Resource Hints plugin for WordPress is vulnerable to SQL Injection via an unknown parameter in all versions before 1.8.19 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Note that the vulnerability appears to have been patched without a version update - users on version 1.8.19 should reinstall the plugin to ensure that they are running the patched version.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Pre* Party Resource Hints < 1.8.19 takes an account at Administrator level or above. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Pre* Party Resource Hints the fix is 1.8.19: builds < 1.8.19 are affected, anything from 1.8.19 onward is not.

Remediation

Update to version 1.8.19, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pre* Party Resource Hints 1.8.19 closes this, and updating the plugin is the step that ends it.
