What to do
AI-suggested
- Immediately restrict administrative access to the Wavlink AC3000 web interface by limiting it to trusted IP addresses or internal networks only.
- Enforce strong, unique passwords and implement multi-factor authentication if supported to reduce the risk of credential compromise.
- Monitor network traffic for unusual HTTP POST requests targeting nas.cgi endpoints, particularly those with suspicious disk_part parameters.
- Disable remote management features if not required to minimize exposure.
- Regularly audit router firmware versions and configurations to identify affected devices.
- Engage with Wavlink support or vendor channels to obtain and apply firmware updates or patches as soon as they become available.
- Consider network segmentation to isolate vulnerable devices from critical infrastructure.
- Employ intrusion detection systems (IDS) or endpoint detection and response (EDR) solutions capable of detecting anomalous command injection attempts.
- Educate network administrators on this vulnerability and the importance of credential security.
- Prepare incident response plans to quickly remediate any detected exploitation attempts.
Description
Multiple command execution vulnerabilities exist in the nas.cgi add_dir() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary command execution. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A command injection vulnerability exists in the disk_part POST parameter.
