This Metasploit module exploits a stack overflow in the A5AGU.SYS driver provided with the D-Link DWL-G132 USB wireless adapter. This stack overflow allows remote code execution in kernel mode. The stack overflow is triggered when a 802.11 Beacon frame is received that contains a long Rates information element. This exploit was tested with version 1.0.1.41 of the A5AGU.SYS driver and a D-Link DWL-G132 USB adapter (HW: A2, FW: 1.02). Newer versions of the A5AGU.SYS driver are provided with the D-Link WUA-2340 adapter and appear to resolve this flaw, but D-Link does not offer an updated driver for the DWL-G132. Since this vulnerability is exploited via beacon frames, all cards within range of the attack will be affected. The tested adapter used a MAC address in the range of 00:11:95:f2:XX:XX.
