SQL Injection Cheat Sheet OWASP

The most famous form of injection is SQL Injection where an attacker can modify existing database queries. For more information see the SQL Injection Prevention Cheat Sheet . But also LDAP, SOAP, XPath and REST based queries can be susceptible to injection attacks allowing for data retrieval or control bypass It represents a serious threat because SQL Injection allows evil attacker code to change the structure of a web application's SQL statement in a way that can steal data, modify data, or potentially facilitate command injection to the underlying OS. This cheat sheet is a derivative work of the SQL Injection Prevention Cheat Sheet

Overview. A SQL injection attack consists of insertion or injection of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the. For more information see the SQL Injection Prevention Cheat Sheet. But also LDAP, SOAP, XPath and REST based queries can be susceptible to injection attacks allowing for data retrieval or control bypass. SQL Injection. An SQL injection attack consists of insertion or injection of either a partial or complete SQL query via the data input or transmitted from the client (browser) to the web. This cheat sheet provides guidance on securely configuring and using the SQL and NoSQL databases.

  4. Blind SQL injection is nearly identical to normal SQL Injection, the only difference being the way the data is retrieved from the database. When the database does not output data to the web page, an attacker is forced to steal data by asking the database a series of true or false questions. This makes exploiting the SQL Injection vulnerability more difficult, but not impossible.
  5. For more details on how to specifically defend against SQL Injection, please refer to OWASP's SQL Injection Prevention Cheat Sheet. Another strong protection against injection attacks is to ensure that the web application runs with only the privileges it absolutely needs to perform its function
