SolisCloud IDOR Vulnerability: CVE-2025-13932 Exposes Plant Data

Overview

CVE-2025-13932 describes a Broken Access Control vulnerability, specifically an Insecure Direct Object Reference (IDOR), found in the SolisCloud API. This flaw allows any authenticated user to access detailed data of any plant managed within the SolisCloud platform. By simply altering the plant_id parameter in API requests, an attacker can bypass intended access controls and view sensitive information of other users’ plants.

This vulnerability was published on 2025-12-04T22:15:47.353.

Technical Details

The SolisCloud API uses the plant_id parameter to identify and retrieve information about specific plants. The vulnerability lies in the lack of proper authorization checks to ensure that the authenticated user is authorized to access data associated with the requested plant_id. An attacker can exploit this by:

1. Authenticating to the SolisCloud API with their own credentials.
2. Identifying an API endpoint that retrieves plant details using the plant_id parameter.
3. Modifying the plant_id parameter in the API request to a different, valid plant_id belonging to another user’s plant.
4. Sending the modified request. If successful, the API will return detailed information about the plant associated with the modified plant_id, even though the authenticated user does not have permission to access it.

Example API request (vulnerable):

        GET /api/plant/details?plant_id=12345 HTTP/1.1
        Host: api.soliscloud.com
        Authorization: Bearer [Your Authentication Token]
        

An attacker could change plant_id=12345 to plant_id=67890 and potentially access data belonging to a different user.

CVSS Analysis

Currently, a CVSS score is not available for CVE-2025-13932. However, given the nature of the vulnerability (Broken Access Control/IDOR) and the potential for exposure of sensitive plant data, it is likely to be rated as Medium to High severity. A CVSS score in the range of 6.0 to 8.9 would be reasonable, depending on the specific data exposed and the ease of exploitation. Further analysis will be needed as more information becomes available.

Possible Impact

The exploitation of CVE-2025-13932 could have significant consequences:

• Data Breach: Attackers could gain access to sensitive information about solar panel installations, including location data, energy production statistics, and potentially customer details depending on the data stored within SolisCloud.
• Competitive Advantage: Competitors could gather intelligence about the performance of different solar panel installations.
• Reputational Damage: Exposure of this vulnerability could damage SolisCloud’s reputation and erode customer trust.

Mitigation or Patch Steps

The primary mitigation strategy is for SolisCloud to implement robust access control checks in their API. Specifically:

• Implement Proper Authorization Checks: Before returning plant data, the API must verify that the authenticated user has explicit permission to access the requested plant_id. This can be achieved through Role-Based Access Control (RBAC) or Access Control Lists (ACLs).
• Avoid Direct Object References: Consider using indirect references (e.g., GUIDs) instead of exposing internal IDs like plant_id directly in the API.
• Rate Limiting: Implement rate limiting to prevent attackers from rapidly iterating through different plant_id values.
• Logging and Monitoring: Implement comprehensive logging and monitoring to detect and respond to suspicious API activity.
• Apply the Patch: SolisCloud should release a patch that addresses this vulnerability. Users of SolisCloud should apply the patch as soon as it becomes available. Check for official announcements and updates from SolisCloud.
