Description:
A vulnerability has been reported in Cisco Aironet Wireless AP (Access Point), which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the handling of spoofed ARP messages. This can be exploited by sending spoofed ARP messages to the management interface of the AP to continuously add entries to the ARP table of the device until the device runs out of memory.
Successful exploitation causes the AP to be unable to pass traffic until the device is restarted, but requires the ability to send ARP messages to the management interface of the AP.
The vulnerability has been reported in the following APs that run Cisco IOS Software:
* Cisco Aironet 1400 Series Wireless Bridges
* Cisco Aironet 1300 Series Access Points
* Cisco Aironet 1240AG Series Access Points
* Cisco Aironet 1230AG Series Access Points
* Cisco Aironet 1200 Series Access Points
* Cisco Aironet 1130AG Series Access Points
* Cisco Aironet 1100 Series Access Points
* Cisco Aironet 350 Series Access Points running IOS
Note: Cisco Wireless devices running a VxWorks based image (Version 12.05 and earlier) are reportedly not vulnerable.
