Ensure Database and Application User Input is Sanitized
Descrição
Always validate user input received from a database client or application by testing type, length, format, and range prior to transmitting it to the database server.
Como é verificado
Método de auditoria: Revisão manual
Check with the application teams to ensure any database interaction is through the use of stored procedures and not dynamic SQL. Revoke any INSERT, UPDATE, or DELETE privileges to users so that modifications to data must be done through stored procedures. Verify that there's no SQL query in the application code produced by string concatenation.
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
The following steps can be taken to remediate SQL injection vulnerabilities: ; Review TSQL and application code for SQL Injection ; Only permit minimally privileged accounts to send user input to the server ; Minimize the risk of SQL injection attack by using parameterized commands and stored procedures ; Reject user input containing binary data, escape sequences, and comment characters ; Always validate user input and do not use it directly to build SQL statements
