Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in WP Zinc Page Generator.This issue affects Page Generator: from n/a through 1.7.1.
WP Zinc Page Generator versions up to 1.7.1 are vulnerable to SQL injection, allowing attackers to potentially compromise the database and gain unauthorized access to sensitive information. This vulnerability enables attackers to inject malicious SQL code, leading to data breaches, remote code execution, and complete system takeover. Successful exploitation could result in significant financial and reputational damage.
Step 1: Payload Delivery: An attacker identifies a vulnerable parameter within the WP Zinc Page Generator plugin, likely a field used for filtering, sorting, or searching data.
Step 2: Payload Injection: The attacker crafts a malicious SQL payload, such as a string designed to extract data, bypass authentication, or execute arbitrary commands on the database server. This payload is inserted into the vulnerable parameter.
Step 3: Query Execution: The plugin's code constructs an SQL query using the attacker-supplied input without proper sanitization. The malicious payload is directly incorporated into the query string.
Step 4: Database Interaction: The crafted SQL query, now containing the attacker's payload, is executed by the database server.
Step 5: Data Exfiltration/Exploitation: Depending on the payload, the attacker can extract sensitive data (e.g., usernames, passwords, customer information), modify database contents, or potentially achieve remote code execution on the server.
The vulnerability lies in the WP Zinc Page Generator plugin's failure to properly sanitize user-supplied input before incorporating it into SQL queries. Specifically, the plugin likely constructs SQL queries dynamically, concatenating user-provided data directly into the query strings without proper escaping or validation. This allows an attacker to inject malicious SQL commands, such as UNION SELECT, DROP TABLE, or UPDATE statements, to manipulate the database. The root cause is a lack of input validation and output encoding, leading to the improper neutralization of special characters within the SQL query context. The absence of parameterized queries or prepared statements further exacerbates the issue, making the plugin susceptible to SQL injection attacks.
