CVE-2023-1387
CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Grafana versions 9.1 and later
Description
The issue is related to the ability to search for a JWT in the URL query parameter
auth token and use it as the authentication token. By enabling the "url login" configuration option, a JWT might be sent to data sources. If an attacker has access to the data source, the leaked token could be used to authenticate to Grafana. This could allow a remote attacker to gain unauthorized access to protected information.Recommendations
For Grafana versions 9.1 and later, consider disabling the "url login" configuration option to prevent JWT tokens from being sent to data sources. As a temporary workaround, restrict access to data sources to minimize the risk of exploitation. Avoid using the
auth token parameter in URL queries until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
