CVE-2008-5230 Information

Description

The Temporal Key Integrity Protocol (TKIP) implementation in unspecified Cisco products and other vendors’ products as used in WPA and WPA2 on Wi-Fi networks has insufficient countermeasures against certain crafted and replayed packets which makes it easier for remote attackers to decrypt packets from an access point (AP) to a client and spoof packets from an AP to a client and conduct ARP poisoning attacks or other attacks as demonstrated by tkiptun-ng.
