A stack-based buffer overflow vulnerability exists in the urvpn_client http_connection_readcb functionality of Milesight UR32L v32.3.0.5. A specially crafted network packet can lead to a buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.
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.
The product writes data past the end, or before the beginning, of the intended buffer.
