Question
After an SQL Injection attack, an investigator is examining a log entry in an IIS log from a Windows-based server. The investigator notices a suspicious GET request: Id=ORD-001%27%20or%201=1;–. What can the investigator infer from this decoded query in the investigation?
A. The attack has attempted to extract database and table names
B. The attack was made from a Linux machine
C. The attack has bypassed authentication to access sensitive data from the database
D. The attack is trying to retrieve the number of columns that are vulnerable to attack
Answer
C. The attack has bypassed authentication to access sensitive data from the database
Explanation
The given suspicious GET request in the IIS log is: Id=ORD-001%27%20or%201=1;–
Decoding this query: Id=ORD-001′ or 1=1;–
The query can be broken down as follows:
- Id=ORD-001′: The initial part of the SQL query, which might be a legitimate request.
- or 1=1: A typical SQL injection payload that always evaluates to true.
- ;–: This ends the legitimate SQL query and comments out the rest of the SQL statement.
Inference: Option C: The attack has bypassed authentication to access sensitive data from the database.
Reasoning:
Bypassing Authentication:
The payload or 1=1 is a common technique used in SQL injection attacks to bypass authentication. By adding or 1=1, the condition always evaluates to true, which means the SQL server will process the query as valid and grant access without proper authentication.
Sensitive Data Access:
Once authentication is bypassed, attackers can potentially access sensitive information stored in the database. This type of injection can expose confidential data without proper security checks.
Other Options Analysis:
A. Extract Database and Table Names: This specific query does not indicate attempts to enumerate databases or tables; rather, it aims to bypass authentication.
B. Attack from a Linux Machine: The log entry does not provide information about the attacker’s operating system.
D. Retrieve Vulnerable Columns: The query does not suggest efforts to determine the number of columns. Such attacks typically involve ORDER BY or UNION SELECT statements to discover column counts.
Therefore, the investigator can conclude that the SQL injection attack attempted to bypass authentication and potentially access sensitive data from the database.
