Can you explain this vulnerability to me?

This vulnerability is a SQL Injection issue in hitsz-ids airda version 0.0.3, specifically in the /v1/chat/completions endpoint's execute function. It arises because user input provided via the 'question' parameter is directly incorporated into a prompt sent to a Large Language Model (LLM), which generates SQL queries based on this input. The generated SQL is then executed by the application without proper validation or sanitization. An attacker can exploit this by injecting malicious instructions into the 'question' parameter, causing the LLM to produce harmful SQL commands such as deleting data, modifying data, or unauthorized data retrieval. This type of attack is known as Prompt-to-SQL Injection (P2SQL Injection), a variant of SQL Injection. [1, 2, 3]

How can this vulnerability impact me? :

This vulnerability can lead to unauthorized data access, data modification, data deletion, data corruption, and denial of service. Because the malicious SQL generated by the LLM is executed without sufficient validation, attackers can manipulate the system to delete tables, alter data, or retrieve sensitive information. The impact affects the confidentiality, integrity, and availability of the affected system, potentially causing significant damage to data and system operations. [1, 2, 3]

How can this vulnerability be detected on my network or system? Can you suggest some commands?

Detection can focus on monitoring and analyzing requests to the /v1/chat/completions endpoint, specifically looking for suspicious or malicious inputs in the 'question' parameter that could lead to SQL injection. Network or application logs should be inspected for unusual SQL commands generated by the LLM, such as DROP, DELETE, or ALTER statements. Since the vulnerability involves SQL injection via crafted inputs, commands to detect SQL injection attempts or anomalous SQL queries could be used. For example, monitoring HTTP requests with tools like curl or using web application firewalls (WAF) to detect SQL injection patterns. Specific commands might include capturing traffic with tcpdump or Wireshark filtering for POST requests to /v1/chat/completions, or using grep to search logs for keywords like 'DROP TABLE', 'DELETE FROM', or other SQL modification commands. However, no explicit detection commands are provided in the resources. [1, 2, 3]

What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include: 1) Implement strict validation and syntactic parsing of the SQL generated by the LLM to block dangerous operations such as DROP, DELETE without WHERE clauses, and ALTER. 2) Apply a whitelisting mechanism to restrict SQL statements to safe types like SELECT and limit access to specific tables and columns. 3) Modify the prompt engineering to instruct the LLM to generate only safe, non-modifying SQL queries and reject requests involving data modification or deletion. 4) Configure the database user with the principle of least privilege to minimize the impact of any malicious SQL execution. Additionally, since no known countermeasures exist for this specific product version, consider replacing the affected product with an alternative. These steps help reduce the risk of exploitation until a patch or update is available. [2, 3]
