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.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
