What to do

AI-suggested

1. Immediately restrict administrative interface access to trusted IP addresses or VPN connections to reduce exposure. 2. Enforce strong, unique passwords for router administration to prevent credential compromise. 3. Monitor router logs and network traffic for unusual HTTP POST requests targeting adm.cgi or unexpected command execution patterns. 4. Disable remote administration if not required to minimize attack surface. 5. Regularly check Wavlink’s official channels for firmware updates addressing this vulnerability and apply patches promptly once released. 6. Consider network segmentation to isolate vulnerable devices from critical assets. 7. Employ network intrusion detection systems (NIDS) with signatures for command injection attempts targeting Wavlink routers. 8. Educate users about phishing and credential security to prevent attackers from gaining authentication. 9. If patching is delayed, consider replacing affected devices with alternative routers known to be secure. 10. Conduct periodic security assessments of network devices to identify and remediate similar vulnerabilities.

Description

Multiple OS command injection vulnerabilities exist in the adm.cgi sch_reboot() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to a arbitrary code execution. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A command injection vulnerability exists in the `restart_week` POST parameter.
