At a glance

CVE-2014-4944 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the BSK PDF Manager WordPress plugin, affecting versions < 1.5. It carries a CVSS score of 9.9 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 1.5; sites on affected versions should update now. Disclosed August 2014, reported by Claudio Viviani.

Vulnerability Overview

Multiple SQL injection vulnerabilities in inc/bsk-pdf-dashboard.php in the BSK PDF Manager plugin 1.3.2 for WordPress allow remote authenticated users to execute arbitrary SQL commands via the (1) categoryid or (2) pdfid parameter to wp-admin/admin.php.

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 BSK PDF Manager < 1.5 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 BSK PDF Manager the fix is 1.5: builds < 1.5 are affected, anything from 1.5 onward is not.

Remediation

Update to version 1.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to BSK PDF Manager: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: BSK PDF Manager 1.5 closes this, and updating the plugin is the step that ends it.
