At a glance

CVE-2022-3395 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP All Export Pro WordPress plugin, affecting versions <= 1.7.8. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 1.7.9; sites on affected versions should update now. Disclosed October 2022, reported by Sanjay Das Payatu.

Vulnerability Overview

The WP ALL Export Pro plugin for WordPress is vulnerable to SQL Injection via the cc_sql parameter in versions up to, and including, 1.7.8. This allows low-level attackers (depending on whether they have been given permission to perform SQL queries) to to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. While the plugin defaults to allow only administrators to perform such queries, they can also delegate this task to lower-privileged 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 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 WP All Export Pro <= 1.7.8 takes any authenticated account. 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 WP All Export Pro the fix is 1.7.9: builds <= 1.7.8 are affected, anything from 1.7.9 onward is not.

Remediation

Update to version 1.7.9, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP All Export Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP All Export Pro 1.7.9 closes this, and updating the plugin is the step that ends it.
