What to do
AI-suggested
Immediate mitigation should focus on restricting access to the router’s administrative interface to trusted networks and users only, employing strong, unique authentication credentials, and monitoring for suspicious administrative activity. Network segmentation should be enforced to isolate vulnerable devices from critical assets. Since no official patches are currently available, organizations should contact Wavlink support for firmware updates or advisories. If possible, disable the sch_reboot() functionality or any web management features that accept POST requests until a patch is applied. Employ network-level protections such as web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) to detect and block malicious HTTP requests targeting the vulnerable parameter. Regularly audit router firmware versions and configurations across the organization’s network. Educate users and administrators about the risks of credential compromise and enforce multi-factor authentication (MFA) where supported. Finally, maintain up-to-date backups and incident response plans to minimize impact in case of exploitation.
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_hour` POST parameter.
