Technical details

The vulnerability exploits active debug code embedded in the firmware that allows code execution when enabled by an authenticated high-privilege user (CWE-489). Attack vector is local; the attacker must have existing privileged administrative access to the device. Successful exploitation grants root-level operating system access on the switch. Patches are available in firmware versions 1.2412b260707 for V1 and 2.2412b260519 for V2.
