- 漏洞讨论

Cisco VPN 3000 series concentrators are prone to a denial of service condition when handling overly long username/password strings via login pages for the web interface of the device. To exploit this condition, the attacker must submit overly long values for the username/password strings using the POST method. The attacker might, for example, submit a modified version of the form for the login page to trigger this condition.

Successful exploitation will cause the device to reload.

- 漏洞利用

There is no exploit code required. This may be exploited using a text editor and a web browser. It may also be exploited using a web client that has the capability of submitting custom form data manually.

- 解决方案

Cisco has released fixes which address this issue. For Cisco VPN 3002 Hardware Client, this issue is addressed in versions 3.5.5 and 3.6.1 of the firmware.
