Description

CVE-2024-50685 is an Insecure Direct Object Reference (IDOR) vulnerability affecting SunGrow iSolarCloud before the October 31, 2024 remediation. Specifically, the powerStationService API model is susceptible to unauthorized access due to this flaw. While the CVSS score is 9.1 (Critical), the SOCRadar Vulnerability Risk Score (SVRS) is 38, indicating a lower real-world risk than the CVSS score alone suggests. The "In The Wild" tag indicates the vulnerability is being actively exploited by hackers.

Key Insights

1. IDOR Vulnerability: The vulnerability stems from the lack of proper authorization checks when accessing resources through the powerStationService API. This allows attackers to potentially access or modify data related to power stations that they are not authorized to manage.
2. Active Exploitation: The presence of the "In The Wild" tag signifies that attackers are actively exploiting this vulnerability. Although the SVRS score is relatively low, the fact that it's being exploited makes it a higher priority for remediation.
3. Limited Real-World Risk Indication: The SVRS score of 38 contrasts with the CVSS score of 9.1. This suggests that, despite its potential severity, the vulnerability may not be as widely exploited or as easily exploitable as the CVSS score alone would indicate. However, because it is "In The Wild", vigilance is important.

Mitigation Strategies

1. Apply Patch/Upgrade: The primary mitigation is to apply the security patch or upgrade provided by SunGrow that remediates the IDOR vulnerability in the powerStationService API. The Description states that the vulnerability was fixed before October 31, 2024. Ensure systems are upgraded to version after this date.
2. Implement Robust Access Controls: Even after patching, implement more robust access control mechanisms. This includes proper authentication and authorization checks at the API level to ensure that users can only access resources they are explicitly permitted to access. This should involve validating user permissions against each request made to the powerStationService API.
3. Web Application Firewall (WAF) Rules: Deploy or update WAF rules to detect and block malicious requests targeting the vulnerable API endpoint. WAFs can provide an additional layer of defense by identifying and preventing exploitation attempts based on known attack patterns.
4. Monitor for Suspicious Activity: Implement continuous monitoring and logging to detect any suspicious activity related to the powerStationService API. This includes monitoring for unauthorized access attempts, unusual data modifications, or any other anomalous behavior that could indicate exploitation of the vulnerability.
