Grafana Labs Breach Incident Score: Analysis & Impact (GRA2792027112125)

In this Rankiteo incident briefing, we review the Grafana Labs breach identified under incident ID GRA2792027112125.

The analysis begins with a detailed overview of Grafana Labs's information like the linkedin page: https://www.linkedin.com/company/grafana-labs, the number of followers: 254049, the industry type: Software Development and the number of employees: 1742 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 765 and after the incident was 760 with a difference of -5 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Grafana Labs and their customers.

On 19 November 2024, Grafana Labs disclosed Vulnerability, Privilege Escalation and Impersonation issues under the banner "Grafana Enterprise Privilege Escalation Vulnerability (CVE-2025-41115)".

Grafana Labs has disclosed a maximum severity vulnerability (CVE-2025-41115) in its Enterprise product that allows new users to be treated as administrators or enables privilege escalation when SCIM (System for Cross-domain Identity Management) provisioning is enabled.

The disruption is felt across the environment, affecting Grafana Enterprise (Self-Managed).

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Patch Deployment (Grafana Enterprise 12.3.0, 12.2.1, 12.1.3, 12.0.6) and Disabling SCIM Provisioning, and began remediation that includes Software Updates and Configuration Changes (Disabling SCIM), and stakeholders are being briefed through Public Security Bulletin and Customer Advisories.

The case underscores how Resolved (No Evidence of Exploitation in Grafana Cloud), teams are taking away lessons such as Importance of Secure Default Configurations for Preview Features, Rapid Patch Deployment for Critical Vulnerabilities and Proactive Monitoring for Exploitation Attempts (e.g., GreyNoise Scanning Activity), and recommending next steps like Upgrade Grafana Enterprise to patched versions (12.3.0, 12.2.1, 12.1.3, or 12.0.6) immediately, Disable SCIM provisioning if not required and Monitor for unusual SCIM-related activity or privilege escalation attempts, with advisories going out to stakeholders covering Customers advised to apply patches or disable SCIM.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Privilege Escalation tactic, the analysis identified Account Manipulation: Additional Cloud Roles (T1098.003) with high confidence (95%), supported by evidence indicating provision a user with a numeric externalId that maps to an internal account, including administrators and Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with high confidence (90%), supported by evidence indicating improper mapping of the `externalId` SCIM attribute to Grafana’s internal `user.uid`. Under the Persistence tactic, the analysis identified Account Manipulation: SSH Authorized Keys (T1098.004) with moderate to high confidence (70%), supported by evidence indicating compromise administrative accounts, leading to unauthorized dashboard access and Account Manipulation (T1098) with high confidence (95%), supported by evidence indicating privilege escalation or impersonation of administrators when SCIM provisioning is misconfigured. Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating malicious or compromised SCIM client to provision a user with a numeric externalId and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (75%), supported by evidence indicating disabling SCIM Provisioning (as a containment measure, implying attackers could exploit it for evasion). Under the Initial Access tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (85%), supported by evidence indicating exploitation requires both `enableSCIM` and `user_sync_enabled` to be active (misconfigured but valid access path) and Exploit Public-Facing Application (T1190) with moderate to high confidence (80%), supported by evidence indicating prior scanning activity for older Grafana flaws suggests potential reconnaissance. Under the Lateral Movement tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (85%), supported by evidence indicating compromise administrative accounts... leading to lateral movement within enterprise networks. Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application or System Exploitation (T1499.004) with moderate to high confidence (70%), supported by evidence indicating exploitation could disrupt monitoring, alerting, or compliance reporting and Data Destruction (T1485) with moderate confidence (60%), supported by evidence indicating data manipulation (implied by unauthorized admin access). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
