CVE-2024-8118 is a medium-severity vulnerability that affects Grafana. This vulnerability allows for incorrect permission application to the alert rule write API endpoint. As a result, users who possess the permission to write external alert instances are able to also write alert rules, which can lead to unauthorized changes in alert configurations.
The CVSS score for this vulnerability is 5.1, indicating a medium severity level. This score signifies that while the exploit may not be trivial, it poses a considerable risk in certain environments, particularly where sensitive alert rules are configured.
Organizations utilizing Grafana should assess their exposure to this vulnerability, especially if they have users with elevated permissions who could exploit these misconfigurations. Immediate patching is essential to mitigate risks associated with unauthorized alert rule modifications.
The vulnerability was published on September 26, 2024, and has garnered attention due to its potential to impact Grafana installations. Organizations should prioritize remediation efforts to address this vulnerability effectively.
Vulnerability Details
In Grafana, the wrong permission is applied to the alert rule write API endpoint, allowing users with permission to write external alert instances to also write alert rules.
This vulnerability has been classified under CWE-653, which pertains to 'Insufficient Permission Checks'. The CVSS score is 5.1, based on a low attack complexity, a network attack vector, and high privileges required for exploitation.
Technical Analysis
The root cause of CVE-2024-8118 lies in the misconfiguration of permissions within the Grafana alert rule write API. Users with high privileges can exploit this misconfiguration to alter alert rules without proper authorization.
This vulnerability can be exploited through a network attack vector, with low complexity involved in executing the attack. No user interaction is required to exploit this vulnerability, and it has low impacts on confidentiality, integrity, and availability.
Risk & Impact Analysis
Risk to organizations includes unauthorized modifications to alert rules, which can lead to significant disruptions in monitoring and alerting processes. The potential blast radius is considerable, especially in environments where alert rules are critical for operational security.
Organizations should assess the urgency of remediation based on their usage of Grafana and the criticality of the alerts managed through this system. Given the CVSS score of 5.1, organizations should address this vulnerability in their priority patch cycle.
