CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:LRisk Mitigation & User Action
Customers using the affected software are encouraged to implement the risk mitigations below to minimize the risk of vulnerability. Additionally, we encourage customers to combine the risk mitigations with security best practices, also provided below, to deploy a defense-in-depth strategy.
If applying the mitigations noted above are not possible, please see our Knowledgebase article QA43240 - Security Best Practices, for additional recommendations to maintain the security posture of your environment.
- Disable the web server, if possible (This component is an optional feature and disabling it will not disrupt the intended use of the device).
- Configure firewalls to disallow network communication through HTTP/Port 80
- Upgrade to the Micro800 family as this device does not have the web server component.
If applying the mitigations noted above are not possible, please see our Knowledgebase article QA43240 - Security Best Practices, for additional recommendations to maintain the security posture of your environment.
