bsqlbf v2.3 Released – Blind SQL Injection Brute Forcing Tool


This perl script allows extraction of data from Blind SQL Injections. It accepts custom SQL queries as a command line parameter and it works for both integer and string based injections.

We reported bsqlbf when it first hit the net back in April 2006 with bsqlbf v1.1, then the v2.0 update in June 2008. This new update adds much better Oracle support.

Databases supported:

  • MS-SQL
  • MySQL
  • PostgreSQL
  • Oracle

The 6 Attack Models

  • Type 0: Blind SQL Injection based on true and false conditions returned by back-end server
  • Type 1: Blind SQL Injection based on true and error(e.g syntax error) returned by back-end server.
  • Type 2: Blind SQL Injection in “order by” and “group by”.
  • Type 3: extracting data with SYS privileges (ORACLE dbms_export_extension exploit)
  • Type 4: is O.S code execution (ORACLE dbms_export_extension exploit)
  • Type 5: is reading files (ORACLE dbms_export_extension exploit, based on java)

New additions

-type: Type of injection:

3: Type 3 is extracting data with DBA privileges
(e.g. Oracle password hashes from sys.user$)
4: Type 4 is O.S code execution(default: ping 127.0.0.1)
5: Type 5 is Reading O.S files(default: c:\boot.ini)

Type 4 (O.S code execution) supports the following sub types:

-stype: How you want to execute command:

0: SType 0 (default) is based on java,
universal but won’t work against XE
1: SType 1 against oracle 9 with plsql_native_make_utility
2: SType 2 against oracle 10 with dbms_scheduler
