Description

CVE-2024-50687 describes an Insecure Direct Object Reference (IDOR) vulnerability in SunGrow iSolarCloud versions prior to the October 31, 2024 remediation. Specifically, the devService API model is susceptible to this flaw. With a CVSS score of 9.1, the Common Vulnerability Scoring System considers this critical. However, the SOCRadar Vulnerability Risk Score (SVRS) is 38, suggesting a lower level of immediate risk compared to a score above 80. Despite the relatively low SVRS score, the presence of the "In The Wild" tag indicates that this vulnerability is actively exploited by hackers.

Key Insights

1. IDOR Vulnerability: The core issue is an IDOR vulnerability, meaning attackers can potentially access or modify data belonging to other users by manipulating the object references used in API requests. This could lead to unauthorized access to sensitive solar energy system data, including production metrics, configuration settings, and potentially control over the system itself.
2. Impact on Solar Energy Systems: Given that iSolarCloud is a platform for monitoring and managing solar energy systems, exploitation of this vulnerability could have significant consequences. Attackers could manipulate energy production data, disrupt system operations, or even gain control of connected devices.
3. Actively Exploited: Despite the low SVRS, the "In The Wild" tag suggests active exploitation of this vulnerability, heightening the risk despite the numerical SVRS score. This likely indicates limited exploitability or targeted exploitation rather than widespread attacks.
4. Lack of Information on Threat Actors/Exploit Status/CISA Warnings: The information available does not specify particular Threat Actors/APT Groups actively exploiting the vulnerability, active exploits' status, or CISA Warnings associated with CVE-2024-50687.

Mitigation Strategies

1. Apply the October 31, 2024 Remediation: The primary mitigation step is to ensure that the SunGrow iSolarCloud installation is updated with the remediation released on or before October 31, 2024. This patch should address the IDOR vulnerability in the devService API model.
2. Implement Robust Access Controls: Implement robust access controls and input validation on the devService API and all other APIs handling sensitive data. Verify that users only have access to the data they are authorized to view or modify.
3. Monitor API Activity: Implement monitoring and logging of API activity, specifically focusing on requests to the devService API. This will enable the detection of suspicious activity and potential exploitation attempts. Look for unusual patterns in API requests, especially those involving manipulation of object references.
4. Conduct Penetration Testing: Perform regular penetration testing on the iSolarCloud environment to identify and address other potential vulnerabilities. Focus testing efforts on API endpoints and areas handling sensitive data.
