CVE-2023-0507: 
Grafana vulnerability analysis and mitigation

Grafana had a stored XSS (Cross-Site Scripting) vulnerability affecting the core plugin GeoMap, identified as CVE-2023-0507. The vulnerability was discovered during an internal audit and publicly disclosed on February 28, 2023. The issue affected Grafana versions starting from the 8.1 branch, where map attributions weren't properly sanitized, allowing arbitrary JavaScript execution in the context of the authorized user (Grafana Advisory, NVD).

The vulnerability stems from improper sanitization of map attributions in the GeoMap plugin, which allowed storing unsanitized HTML that could execute arbitrary JavaScript code. The vulnerability requires an attacker to have Editor role privileges to exploit by changing a panel to include malicious map attribution content. The issue has been assigned a CVSS score of 5.4 (Medium) with the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N (NetApp Advisory).

Successful exploitation of this vulnerability could lead to vertical privilege escalation, where a user with Editor role could potentially change passwords for users with Admin role if the admin user views a compromised dashboard. This could result in unauthorized access to sensitive information and the ability to add or modify data within the Grafana instance (Grafana Advisory).

Users are advised to upgrade to Grafana versions 8.5.21, 9.2.13, or 9.3.8 or later to receive the security fix. These versions properly sanitize map attributions in the GeoMap plugin to prevent stored XSS attacks (Grafana Advisory).
