Critical Flaw in SolisCloud API Threatens Energy Sector Security
The SolisCloud Monitoring Platform, a widely used solution for managing solar energy systems, has been found to contain a severe authorization bypass vulnerability. Tracked as CVE-2025-13932, this flaw enables attackers to exploit Insecure Direct Object Reference (IDOR) weaknesses in the platform’s API, granting unauthorized access to sensitive energy data. With a CVSS v4 score of 8.3, this vulnerability demands immediate attention from organizations relying on SolisCloud for energy monitoring.
---
Key Points
- Vulnerability Type: Authorization Bypass Through User-Controlled Key (CWE-639), specifically an IDOR flaw.
- Affected Systems: SolisCloud Monitoring Platform (Cloud API & Device Control API) versions API v1 and API v2.
- Severity: CVSS v4 score of 8.3 (High), with a CVSS v3.1 score of 7.7.
- Exploitation Risk: Remotely exploitable with low attack complexity; no user interaction required.
- Impact: Attackers can access detailed energy plant data by altering the `plant_id` in API requests.
- Vendor Response: SolisCloud has not responded to mitigation requests from CISA.

Technical Details
#### Affected Products
The vulnerability impacts the following versions of the SolisCloud Monitoring Platform:
- Cloud API (v1 and v2)
- Device Control API (v1 and v2)
#### Vulnerability Overview
The flaw stems from a Broken Access Control issue, where the API fails to validate user permissions properly. Specifically, it allows any authenticated user to access data from any energy plant by modifying the `plant_id` parameter in API requests. This type of vulnerability, known as Insecure Direct Object Reference (IDOR), is a common but dangerous oversight in API security.

Mitigation Steps
SolisCloud has not yet released a patch for this vulnerability. However, CISA recommends the following defensive measures to minimize risk:
#### Immediate Actions
1. Restrict Network Exposure:
- Ensure control system devices and APIs are not accessible from the internet.
- Follow CISA’s guidelines on [securing ICS devices](https://www.cisa.gov/uscert/ics/alerts/ICS-ALERT-10-301-01).
2. Isolate Control Systems:
- Place control system networks and remote devices behind firewalls.
- Isolate them from business networks to prevent lateral movement by attackers.
3. Secure Remote Access:
- Use Virtual Private Networks (VPNs) for remote access, ensuring they are updated to the latest version.
- Note that VPNs are only as secure as the devices connected to them.
4. Monitor for Suspicious Activity:
- Implement intrusion detection systems (IDS) to monitor for unusual API requests or unauthorized access attempts.
- Follow CISA’s [recommended practices for ICS security](https://www.cisa.gov/resources-tools/resources/ics-recommended-practices).
#### Long-Term Recommendations
- Contact SolisCloud Support: Users of affected versions should reach out to [SolisCloud customer support](https://www.solisinverters.com/uk/contactus.html) for updates on a potential patch.
- Perform Risk Assessments: Conduct a thorough impact analysis before deploying defensive measures.
- Educate Employees: Train staff on social engineering attacks and safe email practices to prevent phishing attempts.

Attack Vector
The vulnerability can be exploited through the following steps:
1. Authentication: An attacker gains access to a valid user account (e.g., through phishing or credential stuffing).
2. API Manipulation: The attacker modifies the `plant_id` parameter in API requests to access data from any energy plant.
3. Data Exfiltration: Sensitive information, such as energy production metrics or customer data, is extracted without authorization.
