At a glance

CVE-2007-4154 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WordPress 2.2 WordPress release line, affecting 2.0.10 – 2.2.1 · 2 branches. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.0.11; sites on affected versions should update now. Disclosed August 2007.

Vulnerability Overview

SQL injection vulnerability in options.php in WordPress 2.2.1 allows remote authenticated administrators to execute arbitrary SQL commands via the page_options parameter to (1) options-general.php, (2) options-writing.php, (3) options-reading.php, (4) options-discussion.php, (5) options-privacy.php, (6) options-permalink.php, (7) options-misc.php, and possibly other unspecified components.

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 WordPress 2.2 2.0.10 – 2.2.1 · 2 branches takes a caller who can reach the endpoint. 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 WordPress 2.2 the fix is 2.0.11: builds 2.0.10 – 2.2.1 · 2 branches are affected, anything from 2.0.11 onward is not.

Remediation

Update to one of the following versions, or a newer patched version: 2.0.11, 2.2.2

How does WordSec protect against this?

The attempt arrives as an ordinary request to WordPress 2.2: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: updating to 2.0.11 is the step that ends it.
