AI Analysis
Technical Summary
This vulnerability in coolercontrold <4.0.0 arises from missing authentication controls on critical functions, enabling unauthenticated remote attackers to access and alter sensitive data through HTTP requests. The CVSS 3.1 base score is 5.9, reflecting a medium severity with local attack vector, low attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. No official fix or patch has been disclosed, and the product is not a cloud service, so remediation depends on vendor updates.
Potential Impact
The vulnerability allows unauthorized users to both view and modify sensitive data within the affected coolercontrold service. This can lead to confidentiality breaches, integrity violations, and potential availability issues. However, exploitation requires local access (AV:L), and the attack complexity is low. There are no known exploits in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to the affected coolercontrold service to trusted users only and monitor for unauthorized access attempts. Avoid exposing the service to untrusted networks.
