WordPressi lisas Ninja Forms, millel on \u00fcle miljoni aktiivse kasutuse, avastati kriitiline haavatavus (CVE pole veel m\u00e4\u00e4ratud), mis v\u00f5imaldab volitamata k\u00fclastajal saada t\u00e4ieliku kontrolli saidi \u00fcle. Probleem on lahendatud versioonides 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 ja 3.6.11. T\u00e4heldatakse, et haavatavust on juba kasutatud r\u00fcnnakute tegemiseks ja selle kiireks peatamiseks on WordPressi platvormi arendajad algatanud kohustusliku automaatse uuenduse installimise kasutajate saitidele. <\/p>\n

Haavatavus tuleneb Merge Tags funktsionaalsuse rakendamise veast, mis v\u00f5imaldab autentimata kasutajatel kutsuda v\u00e4lja teatud statiilise meetodi erinevates Ninja Forms klassides (meetodite mainimise kontrollimiseks edastatud Merge Tags andmetes kutsuti v\u00e4lja meetod is_callable()). Sealhulgas oli saadaval meetodi v\u00e4ljakutse, mis teostas kasutajalt edastatud sisu deserialiseerimist. R\u00fcndaja sai spetsiaalselt vormistatud serialiseeritud andmete edastamise kaudu asendada oma objekte ja k\u00e4ivitada PHP-koodi serveris<\/a> v\u00f5i kustutada juhuslikke faile saidi andmekatalooge.
