SQL इंजेक्शन - शीर्ष वर्डप्रेस सुरक्षा कमजोरियों में से एक और उन्हें कैसे रोकें

व्यवस्थापक

SQL injection is a critical security vulnerability that allows attackers to execute malicious SQL commands on a website's database, potentially exposing or modifying sensitive data. Here's an overview of how SQL injection works in WordPress:

An attacker injects malicious SQL code through user input fields like comment forms, login pages, or search bars[1][2][3]. For example, entering `' OR '1'='1` in a login form could bypass authentication by making the SQL query always evaluate to true[4].

The injected code gets executed by the database, enabling the attacker to perform actions like:

– Viewing private data like user emails, passwords, etc.[1][2][3]

– Modifying or deleting database tables and content[1][3]

– Installing rogue plugins/themes to gain further access[3]

Common entry points include search forms, comment sections, user registration pages – anywhere user input is accepted and not properly sanitized[1][2][3][4].

Preventing SQL injection requires:

– Input validation to remove malicious code[1][2][3]

– Using WordPress' prepared statements for database queries[4]

– Keeping WordPress, themes, and plugins updated[4]

– Implementing a web application firewall (WAF) to monitor and filter requests[1][5]

A WAF like Cloudflare or Sucuri or WP-Firewall can detect and block SQL injection attempts in real-time, providing an essential layer of protection for WordPress sites[1][5].
