AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an Insecure Direct Object Reference (IDOR) in the Moodle OpenAI Chat Block plugin version 3.0.1. It occurs because the blockId parameter in the API endpoint /blocks/openai_chat/api/completion.php is not properly validated. As a result, an authenticated student can impersonate another user's block, such as an administrator's, and send queries that are executed with that block's configuration.
How can this vulnerability impact me? :
The vulnerability can allow an authenticated student to access administrator-only Source of Truth entries, alter the behavior of the AI model, and potentially misuse API resources. This could lead to unauthorized access to sensitive information and manipulation of system behavior.
