A stack-based buffer overflow vulnerability exists in protocol gateways' account management interface. The vulnerability is caused by insufficient length validation of the `account_name` parameter when processing account management requests. An attacker authenticated as a read-only user to the web management interface could supply a specially crafted account name that exceeds the size of the internal stack buffer, resulting in corruption of program execution flow. Successful exploitation could allow an attacker to read sensitive information from device memory, including credentials, modify arbitrary memory contents, and disrupt device availability.
