Code Injection

---

Code injection is the malicious injection or introduction of code into an application. The code introduced or injected is capable of compromising database integrity and/or compromising privacy properties, security and even data correctness. Code injection can also result in data loss or corruption, denial of access and sometimes lead to complete host takeover. Code injection techniques are popular in system hacking or cracking to gain information, privilege escalation or unauthorized access to a system. Code injection attacks can plague applications that depend on user input for execution.
