List of CVEs: CVE-2020-10923, CVE-2020-10924

This module targets ZDI-20-704 (aka CVE-2020-10924), a buffer overflow vulnerability in the UPNP daemon (/usr/sbin/upnpd), on Netgear R6700v3 routers running firmware versions from V1.0.2.62 up to but not including V1.0.4.94, to reset the password for the 'admin' user back to its factory default of 'password'. Authentication is bypassed by using ZDI-20-703 (aka CVE-2020-10923), an authentication bypass that occurs when network adjacent computers send SOAPAction UPnP messages to a vulnerable Netgear R6700v3 router. Currently this module only supports exploiting Netgear R6700v3 routers running either the V1.0.0.4.82_10.0.57 or V1.0.0.4.84_10.0.58 firmware, however support for other firmware versions may be added in the future. Once the password has been reset, attackers can use the exploit/linux/telnet/netgear_telnetenable module to send a special packet to port 23/udp of the router to enable a telnet server on port 23/tcp. The attacker can then log into this telnet server using the new password, and obtain a shell as the "root" user. These last two steps have to be done manually, as the authors did not reverse the communication with the web interface. It should be noted that successful exploitation will result in the upnpd binary crashing on the target router. As the upnpd binary will not restart until the router is rebooted, this means that attackers can only exploit this vulnerability once per reboot of the router. This vulnerability was discovered and exploited at Pwn2Own Tokyo 2019 by the Flashback team (Pedro Ribeiro + Radek Domanski).

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Stability:

  • crash-service-down: Module may crash the service, and the service remains down.

Side Effects:

  • config-changes: Module modifies some configuration setting on the target machine.

Knowledge Base

Vulnerable Application

This module targets ZDI-20-704 (aka CVE-2020-10924), a buffer overflow vulnerability in the UPNP daemon (/usr/sbin/upnpd), on Netgear R6700v3 routers running firmware versions from V1.0.2.62 up to but not including V1.0.4.94, to reset the password for the 'admin' user back to its factory default of 'password'. Authentication is bypassed by using ZDI-20-703 (aka CVE-2020-10923), an authentication bypass that occurs when network adjacent computers send SOAPAction UPnP messages to a vulnerable Netgear R6700v3 router. Currently this module only supports exploiting Netgear R6700v3 routers running either the V1.0.0.4.82_10.0.57 or V1.0.0.4.84_10.0.58 firmware, however support for other firmware versions may be added in the future.

Once the password has been reset, attackers can use the exploit/linux/telnet/netgear_telnetenable module to send a special packet to port 23/udp of the router to enable a telnet server on port 23/tcp. The attacker can then log into this telnet server using the new password, and obtain a shell as the "root" user.

These last two steps have to be done manually, as the authors did not reverse the communication with the web interface. It should be noted that successful exploitation will result in the upnpd binary crashing on the target router. As the upnpd binary will not restart until the router is rebooted, this means that attackers can only exploit this vulnerability once per reboot of the router.

This vulnerability was discovered and exploited at Pwn2Own Tokyo 2019 by the Flashback team (Pedro Ribeiro + Radek Domanski).

The vulnerable firmware versions this exploit supports can be downloaded from the following links: * Netgear R6700v3 firmware version V1.0.4.82_10.0.57 * Netgear R6700v3 firmware version V1.0.4.84_10.0.58

Verification Steps

  1. Connect the R6700v3 router to your local area network and ensure you can access it.
  2. Browse to the admin portal for the router, which will be located by default at http://192.168.1.1.
  3. Go to Advanced -> Administration -> Set Password
  4. Change the password from password to another password of your choice.
  5. Log out and browse again to http://192.168.1.1. Verify that you can log into the router with the new password.
  6. Start msfconsole
  7. Do: use auxiliary/admin/http/netgear_r6700_pass_reset
  8. Set RHOST
  9. Run check and verify that the target is vulnerable.
  10. Do: run
  11. Browse admin portal for the router, and verify you can successfully log in with the username admin and the password password.

Options

RHOSTS

IP address of the LAN interface of the vulnerable target.

RPORT

upnpd port on the target. Default 5000.

Description:
  This module targets ZDI-20-704 (aka CVE-2020-10924), a buffer 
  overflow vulnerability in the UPNP daemon (/usr/sbin/upnpd), on 
  Netgear R6700v3 routers running firmware versions from V1.0.2.62 up 
  to but not including V1.0.4.94, to reset the password for the 
  'admin' user back to its factory default of 'password'. 
  Authentication is bypassed by using ZDI-20-703 (aka CVE-2020-10923), 
  an authentication bypass that occurs when network adjacent computers 
  send SOAPAction UPnP messages to a vulnerable Netgear R6700v3 
  router. Currently this module only supports exploiting Netgear 
  R6700v3 routers running either the V1.0.0.4.82_10.0.57 or 
  V1.0.0.4.84_10.0.58 firmware, however support for other firmware 
  versions may be added in the future. Once the password has been 
  reset, attackers can use the 
  exploit/linux/telnet/netgear_telnetenable module to send a special 
  packet to port 23/udp of the router to enable a telnet server on 
  port 23/tcp. The attacker can then log into this telnet server using 
  the new password, and obtain a shell as the "root" user. These last 
  two steps have to be done manually, as the authors did not reverse 
  the communication with the web interface. It should be noted that 
  successful exploitation will result in the upnpd binary crashing on 
  the target router. As the upnpd binary will not restart until the 
  router is rebooted, this means that attackers can only exploit this 
  vulnerability once per reboot of the router. This vulnerability was 
  discovered and exploited at Pwn2Own Tokyo 2019 by the Flashback team 
  (Pedro Ribeiro + Radek Domanski).
