AI-suggested

1. Immediately restrict administrative access to the Netgear RAX30 router management interface by limiting it to trusted IP addresses and using VPNs for remote access. 2. Enforce strong, unique passwords and multi-factor authentication where supported to prevent unauthorized authentication. 3. Monitor router logs and network traffic for unusual or suspicious HTTP requests targeting the getblockschedule() functionality or other management endpoints. 4. Disable remote management features if not required to reduce exposure. 5. Segment network infrastructure to isolate critical assets from devices running vulnerable firmware. 6. Regularly check Netgear’s official channels for firmware updates addressing this vulnerability and apply patches promptly once available. 7. Consider replacing affected devices with models that have confirmed security updates if patching is delayed. 8. Conduct internal audits to identify all Netgear RAX30 devices in use across the organization to ensure comprehensive mitigation. 9. Educate IT staff about this vulnerability and the importance of credential hygiene to reduce risk of authenticated exploitation.

Description

A stack-based buffer overflow vulnerability exists in the JSON Parsing getblockschedule() functionality of Netgear RAX30 1.0.11.96 and 1.0.7.78. A specially crafted HTTP request can lead to code execution. An attacker can make an authenticated HTTP request to trigger this vulnerability.
