A successful SQL injection attack can lead to: 1. Data Loss or Corruption: An SQL injection attack can lead to the loss or corruption of sensitive data, which can have serious financial and legal implications for the organization. 2. Compromised Systems: An SQL injection attack can compromis...
Prevention of SQL Injections In-band Injection (Classic) includes Error-Based Injection and Union-based injection. With this type of injection, the attacker uses the same channel to launch and gather information. The biggest vulnerability in this attack is dynamic SQL statements either in a simple...
Blind SQL Injection This approach is often used when classic attack methods do not work. In a blind attack, the attacker sends a manipulated query to the database and analyzes the response. The attack is considered “blind” because the attacker does not receive any direct information from the...
