EXPLOIT

The novish command-line interface, included in the NoviWare software distribution through NW400.2.6 and deployed on NoviSwitch devices, is prone to a buffer overflow in the "show log cli" command. This could be used by a read-only user (monitor role) to gain privileged (root) code execution on the switch via command injection.

Detection & IOCs extracted from sources · hover to see the quote

• → Monitor for command injection patterns (e.g., semicolon-prefixed shell commands) injected via the 'show log cli' CLI command on NoviSwitch devices, which may indicate exploitation of the buffer overflow for privilege escalation. ↗
• → Watch for repeated service crashes and restarts on NoviSwitch devices, as the exploit relies on a watchdog restarting the service after a crash to retry exploitation. ↗
• → Alert on monitor-role (read-only) users executing 'show log cli' commands, especially if followed by unexpected privilege escalation or root-level activity. ↗

• · Affected versions are NoviWare software distribution through NW400.2.6; ensure devices are not running any version at or below this threshold. ↗
