The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2023:4030 advisory.

  • Grafana is validating Azure AD accounts based on the email claim. On Azure AD, the profile email field is not unique and can be easily modified. This leads to account takeover and authentication bypass when Azure AD OAuth is configured with a multi-tenant app. (CVE-2023-3128)

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