Exploitation Methods:

• Command Injection: By crafting a malicious input to the ifname parameter in the apcli_cancel_wps function, an attacker can inject arbitrary commands that will be executed by the router's operating system.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable devices and exploit them en masse, leading to widespread compromise.

3. Affected Systems and Software Versions

Affected Systems:

• NETGEAR RAX5 (AX1600 WiFi Router)

Affected Software Versions:

• Firmware Version: V1.0.2.26

It is crucial to note that other versions of the firmware may also be affected if they share the same codebase. Users should verify the vulnerability status of their specific firmware version.

4. Recommended Mitigation Strategies

Immediate Actions:

• Firmware Update: Users should immediately update their router firmware to the latest version provided by NETGEAR, which includes a patch for this vulnerability.
• Network Segmentation: Isolate the router from critical network segments to limit the potential impact of an exploit.
• Firewall Rules: Implement strict firewall rules to restrict access to the router's web interface from untrusted networks.

Long-Term Strategies:

• Regular Patch Management: Establish a routine for regularly checking and applying firmware updates for all network devices.
• Intrusion Detection Systems (IDS): Deploy IDS to monitor network traffic for suspicious activities that may indicate an exploitation attempt.
• Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.

5. Impact on Cybersecurity Landscape
