CVE-2024-1657
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw was found in the ansible automation platform. An insecure WebSocket connection was being used in installation from the Ansible rulebook EDA server. An attacker that has access to any machine in the CIDR block could download all rulebook data from the WebSocket, resulting in loss of confidentiality and integrity of the system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Ansible rulebook EDA server uses an insecure WebSocket (ws://) connection instead of a secure encrypted connection (wss://). This allows any attacker with network access within the same CIDR block to intercept and download all rulebook data transmitted over the WebSocket, compromising confidentiality and integrity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the EDA server WebSocket endpoint configurationLocate the configuration file or environment variable that defines the WebSocket URL used by the Ansible rulebook EDA server. Common locations include the server configuration file, environment variables (such as ANSIBLE_EDA_WS_URL or similar), or the command-line arguments used to start the EDA server.Affected if The WebSocket URL starts with ws:// instead of wss://
-
Verify the WebSocket connection protocol in useCapture network traffic or inspect the server logs to observe what protocol the EDA server is advertising or accepting for WebSocket connections. Use a tool like tcpdump, Wireshark, or examine server startup logs for the WebSocket endpoint URL.Affected if The server is accepting connections on a ws:// URL rather than wss://
-
Check if TLS/SSL is configured for the WebSocket endpointReview the EDA server configuration files and look for SSL/TLS settings such as key_file, cert_file, or SSL_ENABLED. Also check if the server has any configuration for secure WebSocket (WSS) or TLS certificate paths defined.Affected if No TLS/SSL certificate configuration exists for the WebSocket endpoint, or the configuration explicitly uses an insecure ws:// protocol
-
Inspect network listening servicesRun netstat, ss, or similar tools to list all listening services on the EDA server host. Identify any WebSocket service listening on an unencrypted port (typically 8080 or similar non-SSL ports) rather than a secure port.Affected if The EDA server WebSocket service is listening on a non-SSL port without TLS encryption
The environment is affected if the Ansible rulebook EDA server is configured to use ws:// (unencrypted WebSocket) instead of wss:// (encrypted WebSocket) for transmitting rulebook data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataEnable TLS encryption on the WebSocket connection by configuring WSS (WebSocket Secure) with valid certificates, and implement proper network segmentation or authentication to restrict access to the WebSocket endpoint.
