Description

CVE-2024-50691 is a vulnerability affecting the SunGrow iSolarCloud Android app (version V2.1.6.20241104 and prior) due to missing SSL certificate validation. The application's failure to properly validate SSL certificates makes it susceptible to Man-in-the-Middle (MiTM) attacks, allowing attackers to intercept and manipulate communications between the app and the iSolarCloud server by impersonating the server. Although the CVSS score is 7.4, indicating a high severity, the SOCRadar Vulnerability Risk Score (SVRS) is 30, suggesting a lower level of immediate risk based on SOCRadar's analysis of threat intelligence. This vulnerability is being exploited in the wild.

Key Insights

1. MiTM Attack Surface: The lack of SSL certificate validation directly exposes users to MiTM attacks. A threat actor positioned between the app and the iSolarCloud server can intercept and alter data, potentially gaining access to user credentials, solar panel data, or injecting malicious commands.
2. Data Exposure Risk: Successful exploitation could lead to the exposure of sensitive user data transmitted through the application, including personal information, solar panel configuration details, and energy production data.
3. Compromised System Control: Attackers could potentially manipulate the solar panel system through the compromised app connection, affecting energy production, grid integration, or even causing physical damage in extreme scenarios.
4. Actively Exploited: The vulnerability is actively exploited by hackers.

Mitigation Strategies

1. Mandatory App Update: SunGrow should release an updated version of the iSolarCloud app that includes robust SSL certificate validation to prevent MiTM attacks. Users should be strongly encouraged to update to the latest version immediately.
2. Network Monitoring: Implement network monitoring solutions to detect and alert on suspicious network traffic patterns indicative of MiTM attacks targeting the iSolarCloud app.
3. User Education: Educate users about the risks of connecting to public Wi-Fi networks and encourage them to use trusted networks or VPNs when accessing the app.
4. Web Application Firewall (WAF) and Intrusion Detection/Prevention Systems (IDS/IPS) Rules: For clients hosting iSolarCloud servers, ensure that WAF and IDS/IPS rules are updated to detect and block any exploitation attempts targeting the iSolarCloud infrastructure.
