Vulnerability Description
-------------------------
Certain Precidia Ether232 devices contain memory overwrite and authentication 
flaws.

By making malformed GET requests to the built-in web server on certain Precidia 
Ether232 devices, it is possible to arbitrarily overwrite memory on the device 
and cause unknown impact.

Solution Description
--------------------
At this point in time, Precidia Technologies has not provided a firmware 
upgrade addressing the memory corruption flaw. As a workaround, Precidia 
Technologies suggests that users disable the web server on the device through 
the serial or telnet configuration interface.

Tested Systems / Software (with versions)
------------------------------------------
Precidia Ether3201-232 w/ firmware 3.00.250
Precidia Ether232 Duo w/ firmware 5.00.02
Other versions are believed to be vulnerable.
