At a glance
CVE-2022-0867 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Pricing Table Plugin WordPress plugin, affecting versions <= 3.6. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.6.1; sites on affected versions should update now. Disclosed April 2022, reported by cydave.
Vulnerability Overview
The Pricing Table WordPress plugin before 3.6.1 fails to properly sanitize and escape user supplied POST data before it is being interpolated in an SQL statement and then executed via an AJAX action available to unauthenticated users
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, 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 Pricing Table Plugin <= 3.6 takes no account at all. 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 Pricing Table Plugin the fix is 3.6.1: builds <= 3.6 are affected, anything from 3.6.1 onward is not.
Remediation
Update to version 3.6.1, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pricing Table Plugin 3.6.1 closes this, and updating the plugin is the step that ends it.
