Pesquisadores da JFrog descobriram no Docker image chamado «cabotage-app» um token que oferece acesso administrativo aos reposit\u00f3rios Python, PyPI e Python Software Foundation no GitHub. O token foi encontrado em um arquivo bin\u00e1rio «__pycache__\/build.cpython-311.pyc» com bytecode compilado armazenado em cache.

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

De acordo com representantes do reposit\u00f3rio PyPI, o token foi criado em 2023 para o desenvolvedor ewdurbin (Ee Durbin), que ocupa o cargo de diretor de infraestrutura na organiza\u00e7\u00e3o Python Software Foundation. O token concedia acesso administrativo a todos os reposit\u00f3rios e organiza\u00e7\u00f5es do projeto, incluindo todos os reposit\u00f3rios das organiza\u00e7\u00f5es pypi, python, psf e pypa. A imagem Docker problem\u00e1tica com o token foi publicada no diret\u00f3rio do Docker Hub em 3 de mar\u00e7o de 2023 e removida em 11 de junho de 2024, ou seja, ficou 16 meses dispon\u00edvel ao p\u00fablico. O token foi revogado em 28 de junho. <\/p>\n

\u00c9 not\u00e1vel que nos c\u00f3digos-fonte dispon\u00edveis, com base nos quais o arquivo problem\u00e1tico de bytecode foi gerado, n\u00e3o h\u00e1 men\u00e7\u00e3o ao token. O autor do c\u00f3digo explicou que, durante o desenvolvimento da ferramenta cabotage-app5 em seu sistema local, encontrou limita\u00e7\u00f5es de intensidade no acesso \u00e0 API do GitHub ao realizar a fun\u00e7\u00e3o de upload automatizado de arquivos do GitHub, e para contornar os limites impostos \u00e0s solicita\u00e7\u00f5es an\u00f4nimas ao GitHub, temporariamente adicionou seu token de trabalho ao c\u00f3digo. Antes da publica\u00e7\u00e3o do c\u00f3digo escrito, o token foi removido, mas o desenvolvedor n\u00e3o percebeu que a men\u00e7\u00e3o ao token foi armazenada em cache no arquivo pr\u00e9-compilado de bytecode, que posteriormente foi inclu\u00eddo na imagem do docker. 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

A auditoria de atividade nos reposit\u00f3rios do GitHub realizada pelos desenvolvedores do Python n\u00e3o identificou tentativas de acesso de terceiros utilizando o token exposto. Considerando que desde 2017 o GitHub \u00e9 a plataforma prim\u00e1ria para o desenvolvimento do CPython, a possibilidade de o token cair em m\u00e3os mal-intencionadas poderia levar \u00e0 compromisss\u00e3o total da infraestrutura usada para o desenvolvimento do Python e do reposit\u00f3rio PyPI, al\u00e9m de permitir tentativas de integra\u00e7\u00e3o de backdoors no CPython e no gerenciador de pacotes PyPI. <\/p>\n

O incidente destaca a import\u00e2ncia de analisar vazamentos n\u00e3o apenas no c\u00f3digo-fonte, arquivos de configura\u00e7\u00e3o e vari\u00e1veis de ambiente, mas tamb\u00e9m em arquivos bin\u00e1rios. No contexto do Python, os usu\u00e1rios tamb\u00e9m s\u00e3o aconselhados a prestar aten\u00e7\u00e3o \u00e0 presen\u00e7a de arquivos .pyc com bytecode compilado em projetos carregados, pois esses arquivos podem conter modifica\u00e7\u00f5es ocultas que n\u00e3o est\u00e3o presentes no c\u00f3digo-fonte.
