Delta Electronics AS320T industrial device contains a buffer size calculation vulnerability in its web service GET/PUT request handlers. The incorrect calculation of buffer size on the stack could potentially lead to buffer overflow conditions. This affects the device's web service functionality and may allow attackers to exploit the vulnerability through crafted HTTP requests. The vulnerability is part of a broader security advisory covering multiple CVEs affecting the AS320T device. Given the industrial nature of the affected device and the potential for stack-based buffer issues, this represents a significant security risk for industrial control systems.
