CWE ID Description
CWE-89 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.

Executive Summary

This is a Blind SQL Injection vulnerability in the WP Post Author plugin for WordPress. It allows attackers to manipulate SQL queries by injecting malicious code, potentially accessing or modifying database contents without direct visibility into the results.

Detection Guidance

Detecting SQL injection vulnerabilities typically involves inspecting web application inputs for malicious SQL patterns. Check for unusual database queries, error messages revealing SQL structure, or unexpected behavior when submitting inputs. Use tools like SQLmap to test for blind SQL injection by sending crafted payloads and monitoring responses.

Impact Analysis

An attacker could exploit this to extract sensitive data from your WordPress database, such as user credentials, personal information, or other confidential content. They might also alter or delete data, leading to website disruption or data loss.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection and security. Organizations may face legal penalties, fines, or reputational damage if exploited.

Mitigation Strategies

Immediately update the WP Post Author plugin to the latest version to patch the vulnerability. Disable the plugin if an update is unavailable. Implement input validation and parameterized queries in your web applications to prevent SQL injection. Monitor database logs for suspicious activity.
