Grafana: Improper Neutralization of Special Elements used in a Command
CVE-2024-9264 is a high-severity improper neutralization of special elements used in a command vulnerability in Grafana, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 11.0.5, 11.1.6, 11.2.1 as the first without the flaw, so updating Grafana to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 97.6% chance of exploitation within 30 days, which is in the top 0.1% of all scored CVEs.
Exploitation in the next 30 days is more likely than not, according to EPSS.
What to do
- Update Grafana to 11.0.5 or 11.1.6 or 11.2.1 or 11.0.6, whichever matches your release line, or a later version.
- Read the advisory on grafana.com for workarounds and exact fixed builds.

Official 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.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
