• Key Concepts: 
  ABAP Command Injection is a type of attack that exploits a vulnerability in the ABAP runtime environment. It occurs when an attacker injects malicious code into an ABAP program, allowing them to gain access to sensitive data or execute arbitrary commands on the system. The vulnerability is caused by insufficient input validation and can be exploited by attackers with access to the system. 
  
  How to use it: 
  To prevent ABAP Command Injection attacks, it is important to ensure that all user input is properly validated. This can be done by using input validation functions such as SAP_VALIDATE_INPUT or SAP_CHECK_INPUT. Additionally, it is important to ensure that all user-supplied data is properly sanitized before being used in any ABAP program. 
  
  Tips & Tricks: 
  It is also important to ensure that all ABAP programs are regularly updated and patched to prevent any potential vulnerabilities from being exploited. Additionally, it is important to ensure that all users have the least amount of privileges necessary for their job role. This will help reduce the risk of an attacker gaining access to sensitive data or executing arbitrary commands on the system.
