Vulnerability Overview

The Visitor Traffic Real Time Statistics WordPress plugin before 3.9 does not validate and escape user input passed to the today_traffic_index AJAX action (available to any authenticated users) before using it in a SQL statement, leading to an SQL injection issue

Technical Analysis

REMEDIATION: Update to version 3.9, or a newer patched version --- 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.
