Question
What is the primary difference between SQL Injection and
Command Injection?Solution
SQL Injection manipulates database queries through insecure input handling, compromising data integrity and confidentiality. Command Injection executes arbitrary OS commands, leveraging vulnerabilities in web applications to gain deeper system access. For example:
- SQL Injection: ' OR 1=1 -- retrieves all database records.
- Command Injection: ; rm -rf / executes a destructive system command.
- Impact of SQL Injection: It compromises database security but doesn’t directly access the OS.
- Impact of Command Injection: Can control the host system, escalating privileges and causing more extensive damage.
- Exploits browsers: Neither attack targets browsers.
- Targets protocols: SQL Injection and Command Injection are unrelated to HTTP or SMTP protocols.
- Disrupts servers/clients: Both can disrupt servers but differ in targets (database vs. OS).
- Harmless comparison: SQL Injection is equally dangerous depending on context.
