CVE-2025-13932
📋 TL;DR
The SolisCloud API has an Insecure Direct Object Reference (IDOR) vulnerability where authenticated users can access detailed data from any solar plant by manipulating the plant_id parameter in API requests. This affects all organizations using the vulnerable SolisCloud API for solar plant management. Attackers can view sensitive operational data from plants they shouldn't have access to.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could access detailed operational data from all solar plants in the system, potentially enabling industrial espionage, operational disruption through data manipulation, or reconnaissance for further attacks.
Likely Case
Unauthorized users accessing sensitive solar plant data including performance metrics, configuration details, and potentially location information, leading to data privacy violations and competitive intelligence gathering.
If Mitigated
Limited exposure of non-critical plant metadata with proper access controls preventing data manipulation or escalation.
🎯 Exploit Status
Requires authentication but exploitation is trivial via parameter manipulation
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-25-338-06
Restart Required: Yes
Instructions:
1. Review CISA advisory ICSA-25-338-06
2. Contact SolisCloud vendor for patch details
3. Apply vendor-provided patch
4. Restart affected services
5. Verify proper access controls are functioning
🔧 Temporary Workarounds
API Access Control Enhancement
allImplement server-side authorization checks for all plant_id parameters
Implement proper session/user context validation in API endpoints
Add authorization middleware checking user permissions against requested plant_id
Network Segmentation
allRestrict API access to authorized networks only
Configure firewall rules to limit API access to trusted IP ranges
Implement VPN for remote access to management interfaces
🧯 If You Can't Patch
- Implement API gateway with strict authorization policies
- Deploy web application firewall with IDOR protection rules
- Enable detailed logging and monitoring of all API requests
- Implement rate limiting and anomaly detection
- Conduct regular access control reviews and audits
🔍 How to Verify
Check if Vulnerable:
Test authenticated API requests with different plant_id values to see if unauthorized access is possibleCheck Version:
Check API version endpoint or contact vendor for version informationVerify Fix Applied:
Attempt the same IDOR attack after patch application to confirm proper authorization checks are in place📡 Detection & Monitoring
Log Indicators:
- Multiple failed authorization attempts for different plant_ids
- Rapid sequential requests to different plant endpoints
- Access patterns showing users accessing plants outside their normal scope
Network Indicators:
- Unusual API request patterns with manipulated plant_id parameters
- High volume of GET requests to plant data endpoints
SIEM Query:
source="api_logs" AND (plant_id_changes > threshold OR unauthorized_access_attempts > 0)
