U slobodnom sustavu za izradu foruma phpBB otkrivena je ranjivost koja omogu\u0107uje putem slanja jednog HTTP zahtjeva povezivanje s sesijom bilo kojeg korisnika foruma. Ranjivost se javlja u zadanoj konfiguraciji phpBB-a. Problem je rije\u0161en u verziji phpBB 3.3.17.<\/p>\n

Napadom na obi\u010dne korisnike mo\u017ee se pristupiti privatnoj komunikaciji i mogu\u0107nostima slanja poruka u ime korisnika. Napadom na moderatore i administratore mo\u017ee se brisati tu\u0111e poruke, pregledavati IP adrese<\/a> i email, \u010ditati privatnu prepisu, ali se ne mo\u017ee u\u0107i u administratorsko su\u010delje i dobiti pristup hostu. <\/p>\n

Detalji o ranjivosti nisu navedeni, ali uz pomo\u0107 AI temeljene na ispravci ponovno je osmi\u0161ljen metod eksploatacije, koji se temelji na pozivu na handler «login_link» s postavljanjem metode autentifikacije «auth_provider=apache» i umetanje korisni\u010dkog imena putem Basic Auth, nakon \u010dega \u0107e PHP postaviti varijablu okru\u017eenja «PHP_AUTH_USER=korisni\u010dko_ime», a phpBB \u0107e iz nje izvu\u0107i korisni\u010dko ime bez provjere lozinke. Na primjer, za dobivanje identifikatora sesije korisnika admin i pohranu u datoteku cookies.txt mo\u017ee se izvr\u0161iti sljede\u0107i kod:<\/p>\n

curl -i -s \
\n -c cookies.txt \
\n -b cookies.txt \
