Summary

Stack-based buffer overflow in the SMASH-CLP shell. An authenticated attacker with SSH access to the BMC can exploit a stack buffer overflow via a crafted SMASH command, overwrite the return address and registers, and achieve arbitrary code execution on the BMC firmware operating system.

Risk Assessment

An attacker with SSH access to the BMC can achieve arbitrary code execution on the management controller, potentially leading to full server management takeover.

Recommendation

Apply the BMC firmware update containing the fix and restrict SSH access to the BMC to trusted networks.
