What to do
AI-suggested
1. Immediately isolate affected Ubiquiti U6-LR devices running firmware 6.6.65 from untrusted or public networks to prevent unauthorized access. 2. Avoid using factory-reset or uninitialized devices in production environments until the vulnerability is addressed. 3. Monitor network traffic and device logs for unusual authentication attempts or root access activities. 4. Implement network segmentation to limit the impact of a compromised device and restrict administrative access to trusted management networks only. 5. Contact Ubiquiti support for guidance and watch for official firmware updates or patches addressing this vulnerability. 6. Consider deploying alternative wireless access points from vendors without known hardcoded credential issues if immediate patching is not feasible. 7. Employ multi-factor authentication and strong network access controls where possible to reduce the risk of lateral movement post-compromise. 8. Maintain an incident response plan tailored to network device compromises to rapidly contain and remediate potential breaches.
Description
Ubiquiti U6-LR 6.6.65 was discovered to contain a hardcoded password vulnerability in /etc/shadow, which allows attackers to log in as root. NOTE: In Ubiquiti's view there is no vulnerability as the Hardcoded Password should be after setup not before.
