CyberRota Analysis
AI-GeneratedThe Socket Firewall in registry mode prior to version 2.0.0 is vulnerable due to its default configuration, which does not verify upstream TLS certificates, allowing attackers to intercept and manipulate traffic. This can lead to the injection of malicious content or alteration of firewall decisions, posing a significant risk to the integrity of package management systems. Organizations using Nginx with this configuration should prioritize addressing this vulnerability by upgrading to version 2.0.0 or later and ensuring proper TLS verification settings are enabled.

Original NVD Description
Socket Firewall (socketdev/socket-registry-firewall) in registry mode before 2.0.0 does not verify upstream TLS certificates by default. When the api_ssl_verify and upstream_ssl_verify configuration keys are omitted from socket.yml, the generated configuration sets SOCKET_API_SSL_VERIFY='false' and UPSTREAM_SSL_VERIFY='false', and the OpenResty/Lua HTTP client used for outbound requests accepts any certificate, including self-signed and otherwise untrusted certificates, without validating the chain. An attacker positioned to intercept traffic between Socket Firewall and the Socket API or an upstream package registry can present a crafted certificate and modify responses in transit, including substituting malicious package content or altering the allow/block decisions the firewall enforces. Setting api_ssl_verify: true and upstream_ssl_verify: true enables verification; however, in versions before 1.1.334, the generated nginx configuration did not emit lua_ssl_trusted_certificate, and thus verification could not be used successfully without manually patching the generated configuration. Version 2.0.0 changes the default for both settings to true.
