V dodatku OptinMonster za WordPress, ki ima ve\u010d kot milijon aktivnih namestitev in se uporablja za prikazovanje pojavnih obvestil in ponudb, je bila odkrito ranljivost (CVE-2021-39341), ki omogo\u010da vstavljanje lastne JavaScript kode na spletno mesto, ki uporablja omenjen dodatek. Ranljivost je odpravljena v izdaji 2.6.5. Da bi blokirali dostop s pomo\u010djo zajetih klju\u010dev po namestitvi posodobitve, so razvijalci OptinMonster razveljavili vse prej ustvarjene API klju\u010de in uvedli omejitve za uporabo klju\u010dev WordPress spletnih mest za spreminjanje kampanj OptinMonster. <\/p>\n

Te\u017eava je bila povzro\u010dena zaradi obstoja REST-API \/wp-json\/omapp\/v1\/support, do katerega je bilo mo\u017eno dostopati brez overitve \u2014 zahteva je bila izvr\u0161ena brez dodatnih preverjanj ob prisotnosti v glavi Referer niza \u201ehttps:\/\/wp.app.optinmonster.test\u201c in ob nastavitvi vrste HTTP-zahteve na \u201eOPTIONS\u201c (to se podredi z uporabo HTTP-glave \u201eX-HTTP-Method-Override\u201c). Med podatki, ki so bili vrnjeni pri dostopu do omenjenega REST-API, je bil prisoten klju\u010d za dostop, ki omogo\u010da po\u0161iljanje zahtevkov katerimkoli obdelovalcem REST-API. <\/p>\n

S pomo\u010djo pridobljenega klju\u010da je mogel napadalec spreminjati katerikoli pojavni blok, ki ga prikazuje OptinMonster, vklju\u010dno z organizacijo izvajanja svoje JavaScript kode. Ko je napadalec pridobil mo\u017enost izvajanja svoje JavaScript kode v kontekstu spletnega mesta, je lahko preusmeril uporabnike na svojo spletno stran ali organiziral nadomestitev privilegiranega ra\u010duna v spletni vmesnik pri izvajanju vstavljenega JavaScript kode s strani skrbnika spletnega mesta. Z dostopom do spletnega vmesnika je lahko napadalec dosegel izvajanje svoje PHP kode na stre\u017enikom<\/a>.
