Anyquery is an SQL query engine built on top of SQLite. Prior to 0.4.5, anyquery server exposes file-backed SQLite virtual table modules such as csv_reader and log_reader through its MySQL-compatible server port without authentication, authorization, or directory restrictions. A remote attacker can use SQLite CREATE VIRTUAL TABLE statements to provide a local path to these modules, which use hashicorp/go-getter under the Anyquery server process and return the selected file contents as queryable table rows. The disclosure is limited only by the filesystem permissions of the server process and can expose system configuration, credentials, and private keys. This issue is fixed in version 0.4.5.

## Summary Anyquery's `server` mode lacks input sanitization and access control over its built-in SQLite virtual table modules (e.g., `csv_reader`, `log_reader`). Unauthenticated attackers connecting to the MySQL-compatible server port can create virtual tables pointing to local files on the system (e.g., `/etc/passwd`, `~/.ssh/id_rsa`). This allows full Local File Read (LFR) capabilities, compromising sensitive system configurations and credentials.

## Details Anyquery utilizes the `hashicorp/go-getter` library within its data ingestion modules. When Anyquery is launched in **Server Mode** (`anyquery server`), it binds to a TCP port and accepts MySQL protocol connections. The server handler does not restrict the usage of these virtual table modules to safe directories. An attacker can connect to the server and execute native SQLite virtual table creation queries to instantiate modules like `csv_reader` pointing to restricted files. Because the file read operation is initiated by the Anyquery server process, the attacker can read any file the process has access to.

## PoC (Proof of Concept) 1. Start the server on the victim machine: ```bash anyquery server --host 0.0.0.0 --port 8070 ``` 2. Connect from an attacker machine: ```bash mysql -u root -h <VICTIM_IP> -P 8070 ``` 3. Execute the following payload to read `/etc/passwd`: ```sql CREATE VIRTUAL TABLE passwd USING csv_reader('/etc/passwd'); SELECT * FROM passwd; ```
