Detailsinfo

A vulnerability was found in miaofng uds-c 2016-10-05. It has been rated as critical. Affected by this issue is the function send_diagnostic_request of the file miaofng/uds-c. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

miaofng/uds-c commit e506334e270d77b20c0bc259ac6c7d8c9b702b7a (2016-10-05) contains a stack buffer overflow in send_diagnostic_request. A 6-byte stack buffer (MAX_DIAGNOSTIC_PAYLOAD_SIZE=6) receives memcpy at offset 1+pid_length with payload_length bytes. MAX_UDS_REQUEST_PAYLOAD_LENGTH=7, so 1+2+7=10 exceeds buffer by 4 bytes. No bounds check on payload_length before memcpy.

This vulnerability is handled as CVE-2026-37536 since 04/06/2026. The exploitation is known to be easy. Access to the local network is required for this attack. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The current price for an exploit might be approx.
