Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Insecure Download: Downloads of critical dependency packages (easy-rsa) originally lacked cryptographic integrity checks, exposing users to potential Man-in-the-Middle (MitM) or supply chain attacks. Standardizing on robust checksum verification is essential.

IP Address Spoofing: Broad interface wildcards in iptables/nftables configurations allowed unvalidated traffic sources, potentially leading to unauthorized packet ingestion and IP address spoofing. Rules must restrict wildcards to explicit source subnets.

Insecure Permissions: Generated .ovpn client configuration files, which contain sensitive private keys and credentials, were created with weak permissions that allowed local users to read them. Files must explicitly restrict read/write access to matching owners.
