GEN:SID | 1:281 |
Message | DOS Ascend Route |
Summary | This event is generated when an attempt is made to issue a Denial of Service (DoS) attack that causes some Ascend routers to reboot.
|
Impact | Denial of Service. Traffic between network segments or between internal and external networks can be disrupted.
|
Detailed Information | Some Ascend routers run configuration software that is able to locate other Ascend routers by broadcasting on UDP port 9 (discard). This port is listened on by the Java Configurator tool. A packet with a specially crafted payload can cause the routers to reboot.
|
Affected Systems | Lucent Ascend MAX Router 5.0 and previous Lucent Ascend Pipeline Router 6.0 and previous Lucent Ascend Pipeline Router 6.0 and previous
|
Attack Scenarios | Ascend routers can be forced to reboot remotely without authorization. Since the offending packet is UDP (which is not connection oriented), the sending address can be easily spoofed.
|
Ease of Attack | Simple. An exploit is available.
|
Corrective Action | An upgrade is available from the manufacturer. Filtering traffic to port 9 will also prevent this exploit.
