Forskere fra JFrog har opdaget en token i Docker-billedet «cabotage-app», som giver administratoradgang til Python, PyPI og Python Software Foundations repositories p\u00e5 GitHub. Tokenet blev fundet i den bin\u00e6re fil «__pycache__\/build.cpython-311.pyc» med det cachenede kompilat.

\"Token<\/center> <\/p>\n

If\u00f8lge repr\u00e6sentanter fra PyPI-repositoriet blev tokenet oprettet i 2023 for udvikleren ewdurbin (Ee Durbin), der er direkt\u00f8r for infrastruktur i Python Software Foundation. Tokenet gav administratoradgang til alle repositoryer og organisationer i projektet, herunder alle repositories fra organisationerne pypi, python, psf og pypa. Det problematiske Docker-billede med tokenet blev offentliggjort i Docker Hub-kataloget den 3. marts 2023 og blev slettet den 11. juni 2024, hvilket betyder, at det var tilg\u00e6ngeligt i 16 m\u00e5neder. Tokenet blev tilbagekaldt den 28. juni. <\/p>\n

Det er bem\u00e6rkelsesv\u00e6rdigt, at der i de tilg\u00e6ngelige kildekoder, som den problematiske fil med bytekode blev genereret ud fra, ikke n\u00e6vnes noget token. Kodeforfatteren forklarede, at han under udviklingen af v\u00e6rkt\u00f8jet cabotage-app5 p\u00e5 sit lokale system st\u00f8dte p\u00e5 begr\u00e6nsninger i API-adgangens intensitet under udf\u00f8relsen af funktionen for automatiseret filupload fra GitHub, og for at omg\u00e5 gr\u00e6nserne for anonyme API-kald til GitHub, tilf\u00f8jede han midlertidigt sit arbejds-token i koden. F\u00f8r han offentliggjorde koden, blev tokenet fjernet, men udvikleren glemte, at omtalen af tokenet var blevet cachet i den forkompilerede bytekodefil, som derefter havnede i docker-billedet. def _fetch_github_file( — github_repository=»owner\/repo», ref=»main», access_token=None, filename=»Dockerfile» + github_repository=»owner\/repo», + ref=»main», + access_token=»0d6a9bb5af126f73350a2afc058492765446aaad», + filename=»Dockerfile», ): <\/p>\n

En revision af aktiviteten i repositories p\u00e5 GitHub foretaget af Python-udviklerne afsl\u00f8rede ikke eksterne fors\u00f8g p\u00e5 adgang ved brug af det afsl\u00f8rede token. Da GitHub siden 2017 har v\u00e6ret den prim\u00e6re platform for udviklingen af CPython, kunne en adgang til tokenet af en ondsindet akt\u00f8r f\u00f8re til en total kompromittering af infrastrukturen, der bruges til udvikling af Python og PyPI-repositoriet, samt muligheden for at fors\u00f8ge at integrere backdoors i CPython og pakkeh\u00e5ndteringssystemet PyPI. <\/p>\n

H\u00e6ndelsen viser vigtigheden af at analysere l\u00e6kager ikke kun i kildekoden, konfigurationsfiler og milj\u00f8variabler, men ogs\u00e5 i bin\u00e6re filer. I konteksten af Python anbefales brugere ogs\u00e5 at v\u00e6re opm\u00e6rksomme p\u00e5 tilstedev\u00e6relsen af pyc-filer med kompileret bytecode i de downloadede projekter, da disse filer kan indeholde skjulte \u00e6ndringer, som ikke findes i kildekoden.
