Linksys WAP4400N request denial of service
| linksys-wap4400n-request-dos (45841) |  Low Risk |
Description:
Linksys WAP4400N is vulnerable to a denial of service, caused by an error when processing association requests while the access point runs in WEP mode. By sending a specially-crafted association request, a remote attacker could exploit this vulnerability to cause the device to reboot.
Platforms Affected:
- Linksys, WAP4400N 1.2.14
- Marvell, Semiconductor 88W8361P-BEM1 chipset
Remedy:
Upgrade to the latest version of WAP4400N (1.2.17 or later), available from the Linksys Web site. See References.
Consequences:

- CVE-2008-4441: The Marvell driver for the Linksys WAP4400N Wi-Fi access point with firmware 1.2.14 on the Marvell 88W8361P-BEM1 chipset, when WEP mode is enabled, does not properly parse malformed 802.11 frames, which allows remote attackers to cause a denial of service (reboot or hang-up) via a malformed association request containing the WEP flag, as demonstrated by a request that is too short, a different vulnerability than CVE-2008-1144 and CVE-2008-1197.
