Marconi ASX-1000 Administration Denial Of Service Vulnerability
ASX-1000 Switches are hardware packages developed by Marconi Corporation. ASX-1000 Switches can be used to regulate ATM networks, performing layer-3 switching. A problem with the switch could allow a management denial of service. The problem occurs in the handling of arbitrary packets with both the SYN-FIN flags set, and fragments. By sending packets of this nature, the services listening on the switch enter close_wait status, and do not reset until the port is reset or the switch is power cycled. This makes it possible for a malicious user to deny administrative access to a switch, and potentially create a network interruption by creating a neccessity to power cycle the switch. This problem affects firmware Forethought 6.2. |
