* Marvell Driver Null SSID Association Request Vulnerability
* The wireless drivers in some Wi-Fi access points (such as the
MARVELL-based Netgear WN802T) do not correctly parse SSID information
element included in association requests. Most information elements are
used by the wireless access point and clients to advertise their
capabilities (regarding rates, network name, cryptographic
capabilities...). More precisely, the SSID is used by the access point
to validate that the wireless client intends to connect to the
* The bug can be triggered by a malicious association request to the
wireless access point with a Null SSID. This can be achieved only after
a successful 802.11 authentication (in "Open" or "Shared" mode according
to the configuration of the wireless access point).
* Denial-of-service (reboot or hang-up) and possibly remote arbitrary
* As it is a wireless driver specific issue, the wireless vendor should
use the latest chipset wireless driver for their access point firmwares.
This security vulnerability was reported to Netgear, updated firmwares
should be available on their web site. Any other wireless device relying
on this vulnerable wireless driver is likely to be vulnerable.
