The web application running on the remote web server is affected by a restriction bypass vulnerability.


According to its self-reported version number, the version of Grafana Enterprise running on the remote host is a version 9.4.x prior to 9.4.17, 9.5.x prior to 9.5.13, 10.0.x prior to 10.0.9 or 10.1.x prior to 10.1.5. It is, therefore, affected by a restriction bypass vulnerability. In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance does not call specific hosts. However, the restriction can be bypassed used punycode encoding of the characters in the request address.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
