How to Fix CVE-2023-22462

To remediate this vulnerability, upgrade all affected Github.com/grafana/grafana dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/grafana/grafana fixed: 9.2.10
Upgrade github.com/grafana/grafana to 9.2.10
github.com/grafana/grafana fixed: 9.3.4
Upgrade github.com/grafana/grafana to 9.3.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/grafana/grafana

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-22462, inspect your project dependencies for Github.com/grafana/grafana:

inspect dependencies for github.com/grafana/grafana

Analyze the terminal output to locate any version of Github.com/grafana/grafana in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.2.10), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Github.com/grafana/grafana, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Description On 2023-01-01 during an internal audit of Grafana, a member of the security team found a stored XSS vulnerability affecting the core plugin "Text". The stored XSS vulnerability requires several user interactions in order to be fully exploited. The vulnerability was possible due to React's render cycle that will pass though the unsanitized HTML code, but in the next cycle the HTML is cleaned up and saved in Grafana's database. ### Impact An attacker needs to have the Editor role in order to change a Text panel to include JavaScript. later, an another user needs to edit the same Text panel, and click on "Markdown" or "HTML" for the code to be executed. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. ### Impacted versions Grafana versions between 9.2.0 and 9.2.10. and between 9.3.0 and 9.3.4 ### Solutions and mitigations Update your Grafana instance. ## Reporting security issues If you think you have found a security vulnerability, please send a report to security@grafana.com.
