FastChat is an open platform by LMSYS for training, serving, and evaluating large language model-based chatbots. It is generally used by entities involved in AI development and research, such as universities, AI-focused startups, and tech companies experimenting with AI implementations. The platform supports chatbot functionalities like those used by Vicuna and Chatbot Arena, providing wide-ranging applications in research and commercial products. Developers leverage FastChat to build and manage conversational AI, making it a critical resource in the AI toolkit. Given its nature, FastChat instances are often deployed on the web for interactive demonstrations and use. This makes it a valuable asset and potential target for inappropriate access or security threats.
This scanner detects the presence of an unauthenticated FastChat Gradio-based web demo instance. Specifically, it recognizes exposed instances titled "Chat with Open Large Language Models" that may be susceptible to unauthorized access. The scanner targets digital footprints indicative of public deployments and seeks out signs of potential misconfigurations. Misconfiguration might allow external access to what is typically an internally managed and protected service. It serves to highlight when an instance might require security hardening due to its potential exposure. Detection ensures organizations can maintain privacy and security around AI model deployments and operation.
Sensitive endpoints include those holding the "Chat with Open Large Language Models" phrase within their web content. The scanner performs a check to see if this particular deployment conveys information that might be classified as sensitive or reveals operational details. A HTTP status of 200 is expected alongside these text matches to confirm operating instances. This specific detection operates based on the reconnaissance of body content within HTTP responses. By confirming both keyword presence and status, the scanner effectively highlights misexposed instances of Gradio services connected to FastChat. Current configurations allow for redirection handling, ensuring the scan remains accurate across various routing scenarios.
If exploited, exposed FastChat instances could lead malicious actors to retrieve sensitive interaction data should these facilities be used in live deployments. This could compromise user privacy and intellectual property, particularly if deployed by companies with proprietary language models. Beyond data exposure, unauthorized access might also interfere with standard operations or inject unapproved queries, skewing intended outcomes. The presence of such vulnerabilities could also erode stakeholders' trust in AI deployments if security perceptions are marred by such oversight. Identifying these instances allows for rectification, safeguarding both user data and company reputation.

Remediation:
- Restrict access to FastChat instances by implementing VPNs or IP whitelisting.
- Ensure all FastChat deployments are authenticated appropriately, requiring user credentials for access.
- Regularly update platform versions to incorporate security patches and enhancements.
- Conduct frequent security audits to pinpoint and correct configuration lapses.
- Train staff to recognize and control the exposure of internal AI resources.
