NETGEAR RAX5 (AX1600 WiFi Router) | V1.0.2.26

How the Exploit Works

The vulnerability arises from a command injection flaw in the ‘apcli_wps_gen_pincode’ function of the device’s firmware. This function is designed to generate a WPS pin code, but it improperly sanitizes the ‘ifname’ parameter. An attacker can exploit this flaw by sending a crafted request containing malicious commands in the ‘ifname’ parameter. As the function does not properly validate this parameter, the injected commands could be executed with root privileges, leading to a complete system compromise.

Conceptual Example Code

Below is a conceptual example demonstrating how this vulnerability might be exploited. This example uses a HTTP POST request to send a malicious command in the ‘ifname’ parameter.

POST /apcli_wps_gen_pincode HTTP/1.1
Host: target_router_ip
Content-Type: application/x-www-form-urlencoded
ifname=`;reboot;`

In this example, the command ‘reboot’ is injected into the ifname parameter. If the request is processed by the vulnerable router, the system would then execute the injected command, causing an immediate reboot of the device. This is a simplistic example; in reality, an attacker could inject far more destructive or malicious commands.

Mitigation

Users of the affected product are urged to update their firmware to the latest version as soon as possible. If a patch is not immediately available, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These can help detect and block malicious requests targeting the vulnerable function. However, these measures should be seen only as stopgaps until a permanent fix is available from the vendor.

How the Exploit Works

The exploit takes advantage of a command injection vulnerability via the ifname parameter in the apcli_do_enr_pin_wps function. An attacker can pass malicious commands embedded in this parameter, which are then executed by the system. This could lead to unauthorized actions being performed, ranging from data exfiltration to a full system compromise.

Conceptual Example Code

An example of how the vulnerability might be exploited is shown below. In this conceptual example, a malicious command is injected via the ifname parameter.

POST /apcli_do_enr_pin_wps HTTP/1.1
Host: target_router_ip_address
Content-Type: application/json
{ "ifname": ";[malicious_command]" }

In the above example, `[malicious_command]` would be replaced by the actual command that the attacker wishes to execute. The semicolon (;) is used to separate commands in many command-line environments, allowing the attacker to append their own command to the ifname parameter.
Please note, this is a conceptual example and may differ from an actual exploit based on the specific implementation and configuration of the router.
