Stack-based buffer overflow in the SMASH-CLP shell.

MEDIUM 5.4EPSS 0.27%

Does this matter?

Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.

Description

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
