• What is the cause and solution for SAP error message /SAPCE/IURU198 - SQL injection error - dynamic access to table &1 with value &2 ?

  The SAP error message /SAPCE/IURU198 indicates a potential SQL injection risk when there is dynamic access to a database table. This error is part of SAP's security measures to prevent SQL injection attacks, which can occur when user input is improperly handled and allows for malicious SQL code to be executed.
  Cause:
  The error is triggered when:
  
  There is dynamic SQL code that accesses a database table.
  The value being passed to the SQL statement is not properly sanitized or validated.
  The system detects that the input could potentially lead to an SQL injection vulnerability.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Code: Check the ABAP code where the dynamic SQL is being constructed. Ensure that all user inputs are properly validated and sanitized before being used in SQL statements.
  
  
  Use Parameterized Queries: Instead of constructing SQL statements dynamically, use parameterized queries or prepared statements. This approach helps to separate SQL logic from data, reducing the risk of SQL injection.
  
  
  Use SAP's Built-in Functions: Utilize SAP's built-in functions for database access, such as SELECT ... INTO TABLE or OPEN SQL, which are designed to handle data safely.
  
  
  Implement Input Validation: Ensure that any user input is validated against expected formats and types. This can include checking for length, type, and allowed characters.
  
  
  Check Authorization: Ensure that the user has the appropriate authorizations to access the data being queried. This can help mitigate risks associated with unauthorized access.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address this specific error or provide additional guidance on securing dynamic SQL access.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the error is resolved and that there are no new issues introduced.
