Cisco ONS15454 Non-Zero TOS Bit Denial Of Service Vulnerability

The ONS15454 is an optical network platform manufactured and distributed by Cisco.

Under some circumstances, it may be possible to stop the ONS15454 from handling traffic. When a packet with a non-zero Type of Service (TOS) is received via the Timing Control Card (TCC) LAN interface, the ONS15454 becomes unstable. The receipt of this type of packet via the TCC interface causes the reset of the TCC interface.
