WordPress Core < 4.8.2 - SQL Injection via Mishandled Placeholders
Strategic Overview
3.7 – 4.8.1 · 13 branchesCVE-2017-14723Vulnerability Overview
Before version 4.8.2, WordPress mishandled % characters and additional placeholder values in $wpdb->prepare, and thus did not properly address the possibility of plugins and themes enabling SQL injection attacks.
Technical Analysis
REMEDIATION: Update to one of the following versions, or a newer patched version: 3.7.22, 3.8.22, 3.9.20, 4.0.19, 4.1.19, 4.2.16, 4.3.12, 4.4.11, 4.5.10, 4.6.7, 4.7.6, 4.8.2 --- IDENTIFIER: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
