The WifiPasswordController generateDefaultPassword method in Preferences in Apple iOS 6 and earlier relies on the UITextChecker suggestWordInLanguage method for selection of Wi-Fi hotspot WPA2 PSK passphrases, which makes it easier for remote attackers to obtain access via a brute-force attack that leverages the insufficient number of possible passphrases.

The WPA2 implementation on the Belkin N900 F9K1104v1 router establishes a WPS PIN based on 6 digits of the LAN/WLAN MAC address, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading broadcast packets, a different vulnerability than CVE-2012-4366.

The D-Link DIR-685 router, when certain WPA and WPA2 configurations are used, does not maintain an encrypted wireless network during transfer of a large amount of network traffic, which allows remote attackers to obtain sensitive information or bypass authentication via a Wi-Fi device.

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.

WeFi 3.2.1.4.1, when diagnostic mode is enabled, stores (1) WEP, (2) WPA, and (3) WPA2 access-point keys in (a) ClientWeFiLog.dat, (b) ClientWeFiLog.bak, and possibly (c) a certain .inf file under %PROGRAMFILES%\WeFi\Users\, and uses cleartext for the ClientWeFiLog files, which allows local users to obtain sensitive information by reading these files.

Buffer overflow in the wpa_printf function in the debugging code in wpa_supplicant in the Fedora NetworkManager package before 0.6.5-3.fc7 allows user-assisted remote attackers to execute arbitrary code via malformed frames on a WPA2 network.
