A stack-based buffer overflow vulnerability exists in the cmd_edl function of OreSat Firmware v1.0. The vulnerability is triggered when processing the edl fw_flash command, where the <filename> argument is copied to a 64-byte stack buffer via memcpy without proper length validation. An attacker with physical access to the UART3 serial interface can exploit this vulnerability by sending a maliciously crafted command with an oversized filename parameter,
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
