HighSummary
W urządzeniach Wavlink WL-NU516U1 do 130/260 zidentyfikowano podatność, która dotyczy funkcji sub_406194 w pliku /cgi-bin/adm.cgi. Manipulacja argumentem firmware_url prowadzi do przepełnienia bufora na stosie, co może być wykorzystane przez atakującego zdalnie.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, ponieważ umożliwia zdalne przejęcie kontroli nad urządzeniem. Publiczne ujawnienie exploita zwiększa prawdopodobieństwo ataku.
Recommendation
Zaleca się natychmiastowe zaktualizowanie urządzeń Wavlink WL-NU516U1 do najnowszej wersji oprogramowania, aby załatać tę podatność. Należy również monitorować ruch sieciowy w celu wykrycia potencjalnych prób ataku.
