Vulnerability Note VU#36312

Cayman gateways are vulnerable to a denial of sevices via a long username or password

Original Release date: 27 Aug 2001 | Last revised: 27 Aug 2001


Cayman gateways are vulnerable to a denial of service via the entry of a long username or password sent to the HTTP interface.


Cayman gateways automatically restart upon the entry of a large(79+ chars) username or password to the HTTP interface. The log will show "restart not in response to admin command". Versions prior to 5.5.0 R1 were vulnerable and if the gateway is not addressable via the WAN, it is exploitable only via the LAN side.


The gateway automatically restarts resulting in a denial of service. This may be the result of a buffer overflow over instructions on the stack.


The fix for the long name entry in the username/password that was originally resolved in 5.5.0 R1 is included in 5.6.2 R5. Upgrade to the latest vendor software release.
