Exam 312-50v13 topic 1 question 238 discussion

Answer: C - use less fequent SQL commands which are not blocked by typical SQLi filters. For example: - MAKE_SET() for string manipulation, - CHAR() / CHR() to build strings from ASCII codes, - HAVING 1=1 --> alternative to WHERE 1=1 ... CEH v12 Student Manual, SQLi Evasion Techniques: "Attackers may use lesser-known SQL statements or DBMS-specific keywords to bypass filters and gain access to backend databases." Incorrect answers: A) Extracting data bit by bit using logical true/false (i. e. 1 or 0) on output from our queries if we can't take data out directly, is possible, but it is not method how to get IN but how to get data OUT. D) OOB channel - again about getting SQLi execution signals and/or data out but this is not technique how to overcome input filters.

Since the e-commerce website already implements input validation and pattern-based filtering to block common SQL injection attempts, an experienced hacker will likely use advanced techniques to bypass these defenses. One such method is Out-of-Band (OOB) SQL Injection, which allows the hacker to extract data through alternate communication channels (such as DNS requests or HTTP responses) instead of relying on the application's direct database responses.
