Associated Vulnerability

Title: Grafana SQL Expressions allow for remote code execution (CVE-2024-9264)
Description:The SQL Expressions experimental feature of Grafana allows for the evaluation of `duckdb` queries containing user input. These queries are insufficiently sanitized before being passed to `duckdb`, leading to a command injection and local file inclusion vulnerability. Any user with the VIEWER or higher permission is capable of executing this attack. The `duckdb` binary must be present in Grafana's $PATH for this attack to function; by default, this binary is not installed in Grafana distributions.

Description

Grafana SQL Expressions → DuckDB LFI (CVE-2024-9264)

Readme

# Day 5 – Grafana SQL Expressions → DuckDB LFI (CVE-2024-9264)

**TL;DR:** On affected Grafana 11.x builds, a logged-in Viewer can use **SQL Expressions**.
Grafana forwards the expression to **DuckDB** on the server. With `read_text()` / `read_blob()`,
you can read local files (LFI). We plant a flag at `/opt/flag.txt`.

## Build → Run
```bash
docker build -t day5-grafana .
docker rm -f day5 2>/dev/null || true
docker run -d --name day5 -p 3000:3000 day5-grafana
