CVE-2024-9264
Description
A vulnerability was found in Grafana. An experimental feature named SQL Expressions was recently added to Grafana to allow query output to be post-processed using SQL. These SQL queries were incompletely sanitized, leading to a command injection and local file inclusion vulnerability. Any user with the VIEWER or higher permission can execute this attack.
Statement
This vulnerability is classified as critical instead of important because it allows for command injection and local file inclusion, potentially leading to arbitrary code execution or unauthorized access to sensitive files. The exploit can be carried out by any user with VIEWER or higher permissions, significantly increasing the attack surface. Moreover, due to an incorrect implementation of feature flags, the SQL Expressions feature is enabled by default for the API, making it more likely to be exposed in affected deployments. Although the vulnerability requires the presence of the DuckDB binary in the Grafana process's PATH, systems that meet this condition are at significant risk.
It’s important to note that this issue was introduced in a Grafana version not included in any Red Hat offerings, ensuring that Red Hat customers are not impacted.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
If a malicious user injects a character (such as a semi-colon) that delimits the end of one command and the beginning of another, it may be possible to then insert an entirely new and unrelated command that was not intended to be executed. This gives an attacker a privilege or capability that they would not otherwise have.
