SunGrow

SunGrow iSolarCloud Android application V2.1.6.20241017 and prior contains hardcoded credentials. The application (regardless of the user account) and the cloud uses the same MQTT credentials for exchanging the device telemetry.

SunGrow WiNet-SV200.001.00.P027 and earlier versions is vulnerable to heap-based buffer overflow due to bounds checks of the MQTT message content.

SunGrow WiNet-SV200.001.00.P027 and earlier versions is vulnerable to stack-based buffer overflow when parsing MQTT messages, due to missing MQTT topic bounds checks.

In SunGrow WiNet-SV200.001.00.P027 and earlier versions, when copying the timestamp read from an MQTT message, the underlying code does not check the bounds of the buffer that is used to store the message. This may lead to a stack-based buffer overflow.

SunGrow iSolarCloud before the October 31, 2024 remediation is vulnerable to insecure direct object references (IDOR) via the userService API model.

SunGrow iSolarCloud before the October 31, 2024 remediation is vulnerable to insecure direct object references (IDOR) via the orgService API model.

SunGrow iSolarCloud before the October 31, 2024 remediation is vulnerable to insecure direct object references (IDOR) via the devService API model.

SunGrow iSolarCloud before the October 31, 2024 remediation is vulnerable to insecure direct object references (IDOR) via the commonService API model.

SunGrow iSolarCloud before the October 31, 2024 remediation, is vulnerable to insecure direct object references (IDOR) via the powerStationService API model.

SunGrow's back end users system iSolarCloud https://isolarcloud.com  uses an MQTT service to transport data from the user's connected devices to the user's web browser.  The MQTT server however did not have sufficient restrictions in place to limit the topics that a user…

In SunGrow WiNet-SV200.001.00.P027 and earlier versions, when decrypting MQTT messages, the code that parses specific TLV fields does not have sufficient bounds checks. This may result in a stack-based buffer overflow.

SunGrow WiNet-S V200.001.00.P025 and earlier versions is missing integrity checks for firmware upgrades. Sending a specific MQTT message allows an update to an inverter or a WiNet connectivity dongle with a bogus firmware file that is located on attacker-controlled server.

SunGrow iSolarCloud Android app V2.1.6.20241104 and prior suffers from Missing SSL Certificate Validation. The app explicitly ignores certificate errors and is vulnerable to MiTM attacks. Attackers can impersonate the iSolarCloud server and communicate with the Android app.

SunGrow iSolarCloud Android app V2.1.6.20241017 and prior uses an insecure AES key to encrypt client data (insufficient entropy). This may allow attackers to decrypt intercepted communications between the mobile app and iSolarCloud.

SunGrow WiNet-SV200.001.00.P027 and earlier versions contains a hardcoded password that can be used to decrypt all firmware updates.

SunGrow WiNet-SV200.001.00.P027 and earlier versions contains hardcoded MQTT credentials that allow an attacker to send arbitrary commands to an arbitrary inverter. It is also possible to impersonate the broker, because TLS is not used to identify the real MQTT broker. This…

A vulnerability, which was classified as problematic, has been found in SunGrow Logger1000 01_A. This issue affects some unknown processing. The manipulation leads to weak password requirements. The attack may be initiated remotely. The complexity of an attack is rather high.…
