[原文]Marconi ForeThought 7.1 allows remote attackers to cause a denial of service by causing both telnet sessions to be locked via unusual input (e.g., from a port scanner), which prevents others from logging into the device.
This vulnerability was reported to Bugtraq by Christopher Kruslicky <firstname.lastname@example.org>.
Marconi ForeThought 7.2
ForeThought is the internetworking software used by most of Marconi's product line. The software incorporates remote administration through telnet and web console interfaces.
The telnet administration interface allows up to two concurrent sessions. When both sessions are locked, the only way to release the sessions is to reboot the device. Until the device is rebooted, access to the telnet interface is not possible.
There is no exploit necessary for this vulnerability.
