"The version of Grafana Labs installed on the remote host is affected by a vulnerability as referenced in the 
CVE-2024-9264 advisory.

  - 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
