At a glance

CVE-2015-7319 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Appointment Booking Calendar WordPress plugin, affecting versions <= 1.1.7. 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 1.1.8; sites on affected versions should update now. Disclosed September 2015, reported by Ibéria Medeiros.

Vulnerability Overview

SQL injection vulnerability in cpabc_appointments_admin_int_calendar_list.inc.php in the Appointment Booking Calendar plugin before 1.1.8 for WordPress allows remote attackers to execute arbitrary SQL commands via unspecified vectors related to updating the username.

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 Appointment Booking Calendar <= 1.1.7 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 Appointment Booking Calendar the fix is 1.1.8: builds <= 1.1.7 are affected, anything from 1.1.8 onward is not.

Remediation

Update to version 1.1.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Appointment Booking Calendar: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Appointment Booking Calendar 1.1.8 closes this, and updating the plugin is the step that ends it.
