Vulnerability Overview

SQL injection vulnerability in wp-trackback.php in Wordpress 1.5 and earlier allows remote attackers to execute arbitrary SQL commands via the tb_id parameter.

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 1.5 < 1.5.1 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 1.5 the fix is 1.5.1: builds < 1.5.1 are affected, anything from 1.5.1 onward is not.

Remediation

Update to version 1.5.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WordPress 1.5: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: updating to 1.5.1 is the step that ends it.
