Summary

The cmd_edl function in OreSat Firmware v1.0 has a stack-based buffer overflow. When processing the edl fw_flash command, the <filename> argument is copied to a 64-byte buffer via memcpy without proper length validation. An attacker with physical access to UART3 can exploit this.

Risk Assessment

Risk of device takeover by an attacker with physical access, potentially leading to unauthorized actions.

Recommendation

Update OreSat Firmware to a version that includes proper length validation for the argument.

Original NVD description (English source)

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,
