What to do
AI-suggested
- Immediately audit all Wavlink AC3000 devices in your environment to identify affected firmware versions (M33A8.V5030.210505).
- Enforce strong, unique administrative passwords to prevent unauthorized authentication.
- Restrict management interface access to trusted IP addresses or via VPN to reduce exposure to authenticated attackers.
- Implement network segmentation to isolate vulnerable devices from critical network segments.
- Monitor network traffic and device logs for unusual HTTP POST requests to nas.cgi or other suspicious activity indicative of exploitation attempts.
- Disable remote management interfaces if not strictly necessary.
- Engage with Wavlink or authorized vendors to obtain and apply firmware updates or patches as soon as they become available.
- Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures targeting command injection attempts on nas.cgi endpoints.
- Educate network administrators about the risks of command injection vulnerabilities and the importance of timely patching and access control.
- Maintain an inventory of all network devices and their firmware versions to facilitate rapid response to emerging threats.
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 adddir_name POST parameter.
