A vulnerability in the web interface of Cisco ONS15454 controller cards could allow an unauthenticated, remote attacker to cause the control card to reset.

The vulnerability is due to incorrect parsing of the HTTP URI. An attacker could exploit this vulnerability by sending specific HTTP requests to the node. An exploit could allow the attacker to trigger a reload of the controller card.

Cisco has confirmed the vulnerability in a security notice and released software updates.

To exploit this vulnerability, an attacker may need access to trusted, internal networks, in which the targeted device may reside, to send HTTP request to the device. This access requirement may reduce the possibility of a successful exploit.
