LOW
The severity is rated as LOW because Capy-Privacy itself does not introduce vulnerabilities but rather mitigates them. The project is designed to enhance security by filtering out harmful content, which reduces the risk of exposure to malicious websites and online threats.

Capy-Privacy is a home DNS filtering project designed to block unwanted internet content at the network level. It leverages DNS resolution to redirect requests for potentially harmful sites to safe alternatives or simply reject them, thereby enhancing the security of a home network. The software aims to provide an easy-to-use and effective solution for families looking to protect their devices from malicious websites, ads, and other online threats. Capy-Privacy's implementation involves setting up a DNS server that filters requests based on predefined lists of blocked domains, ensuring that users cannot access potentially harmful content even if they are not aware of it. This type of filtering can significantly reduce the risk of malware infections and unwanted tracking, making it an essential tool for network security.

Affected Systems
  • Home networks using DNS for resolving internet queries
Affected Versions: N/A - this is an open-source project with continuous development
Remediation
  • Install Capy-Privacy by following the instructions on GitHub: https://github.com/capy-security/capy-privacy#installation
  • Configure your home network's DNS settings to point to the IP address of the server running Capy-Privacy.
  • Periodically update Capy-Privacy to ensure you have access to the latest blocklists and security enhancements.
Stack Impact

Capy-Privacy has a minimal direct impact on homelab stacks as it primarily affects DNS resolution processes. The software should be integrated into the network's DNS configuration, which may require modifying router settings or using specific commands depending on the system version.
