\u00cen serviciul de integrare continu\u0103 Travis CI, destinat test\u0103rii \u0219i construirii proiectelor dezvoltate pe GitHub \u0219i Bitbucket, a fost identificat\u0103 o problem\u0103 de securitate (CVE-2021-41077) care permite accesul la con\u021binutul variabilelor de mediu confiden\u021biale din repositoare publice care utilizeaz\u0103 Travis CI. Aceast\u0103 vulnerabilitate permite, de asemenea, ob\u021binerea cheilor utilizate \u00een Travis CI pentru generarea semn\u0103turilor digitale, a cheilor de acces \u0219i a token-urilor pentru accesarea API-ului. <\/p>\n

Problema a fost prezent\u0103 \u00een Travis CI \u00eentre 3 \u0219i 10 septembrie. Este interesant de remarcat faptul c\u0103 informa\u021biile despre vulnerabilitate au fost transmise dezvoltatorilor pe 7 septembrie, dar \u00een schimb a fost primit\u0103 doar o recomandare de a utiliza rota\u021bia cheilor. Neprimind un r\u0103spuns adecvat, cercet\u0103torii s-au adresat GitHub \u0219i au propus s\u0103 adauge Travis pe lista neagr\u0103. Problema a fost rezolvat\u0103 abia pe 10 septembrie, dup\u0103 numeroase pl\u00e2ngeri din partea diferitelor proiecte. Dup\u0103 incident, pe site-ul companiei Travis CI a fost publicat un raport ciudat despre problem\u0103, care, \u00een loc s\u0103 informeze despre remedierea vulnerabilit\u0103\u021bii, con\u021binea doar recomandarea, men\u021bionat\u0103 f\u0103r\u0103 context, de a schimba periodic cheile de acces. <\/p>\n

Dup\u0103 indignarea cauzat\u0103 de ascunderea informa\u021biilor exprimate de mai multe proiecte majore, pe forumul de suport Travis CI a fost publicat un raport mai detaliat, \u00een care se avertiza c\u0103 proprietarul unui fork al oric\u0103rui repository public, prin trimiterea unei cereri pull, putea ini\u021bia procesul de construire \u0219i ob\u021bine acces neautorizat la variabilele de mediu confiden\u021biale ale repository-ului original, expuse \u00een timpul construirii pe baza c\u00e2mpurilor din fi\u0219ierul <.travis.yml> sau definite prin intermediul interfe\u021bei web Travis CI. Aceste variabile sunt stocate criptat \u0219i sunt decriptate doar \u00een timpul construc\u021biei. Problema afecta doar repository-urile publice care au forks (repository-urile private nu sunt vulnerabile la atac).
