CVE-2008-4441
HighSummary
Sterownik Marvella dla punktu dostępowego Linksys WAP4400N z firmware 1.2.14 na chipsecie Marvell 88W8361P-BEM1, w trybie WEP, nieprawidłowo analizuje źle sformatowane ramki 802.11. To pozwala zdalnym atakującym na wywołanie odmowy usługi (restart lub zawieszenie) poprzez źle sformatowane żądanie asocjacji zawierające flagę WEP.
Risk Assessment
Organizacja narażona jest na ataki, które mogą prowadzić do przerwy w dostępności usług sieciowych, co może wpłynąć na operacje biznesowe. Potencjalne zawieszenie lub restart punktu dostępowego może zakłócić komunikację w sieci.
Recommendation
Zaleca się aktualizację firmware'u punktu dostępowego do najnowszej wersji, która eliminuje tę podatność. Dodatkowo, rozważ wyłączenie trybu WEP na rzecz bardziej bezpiecznych protokołów szyfrowania.

Original NVD description (English source)
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.
