65. A penetration testing report indicated that an organization should implement controls related to database input validation. Which of the following best identifies the type of vulnerability that was likely discovered during the test?
Answer: D
SQL Injection (SQLi) is the type of vulnerability discovered during the test.
The penetration testing report suggests that the organization should implement controls related to database input validation, which directly points to SQL Injection (SQLi) as the likely vulnerability. SQLi occurs when an attacker can manipulate SQL queries through improper input validation, allowing unauthorized access to the database.
A) XSS
Cross-Site Scripting (XSS) involves injecting malicious scripts into web pages viewed by other users. While it is a significant security concern, it is not directly related to database input validation. Instead, XSS exploits vulnerabilities in how applications handle user input in web pages rather than in database queries.
B) Command injection
Command injection vulnerabilities allow attackers to execute arbitrary commands on the host operating system via a vulnerable application. While this is a critical security issue, it does not specifically relate to database input validation, which focuses on SQL commands rather than operating system commands.
C) Buffer overflow
Buffer overflow vulnerabilities occur when an application writes more data to a buffer than it can hold, leading to potential code execution. This type of vulnerability is not associated with database input validation and typically concerns memory management issues rather than SQL queries.
D) SQLi
SQL Injection (SQLi) directly relates to the improper validation of database inputs, allowing attackers to manipulate SQL queries. This can lead to unauthorized data access or manipulation, making it the most relevant type of vulnerability indicated by the need for improved input validation controls.
Conclusion
SQL Injection (SQLi) is the correct answer as it is the vulnerability that arises from inadequate input validation in database queries. The other options, while serious vulnerabilities, do not pertain specifically to database input validation, which is crucial for preventing SQLi attacks. Therefore, the emphasis on implementing input validation controls clearly highlights SQLi as the identified risk.
