Descriptions
A UI misrepresentation vulnerability was identified in GitHub Enterprise Server that allowed more permissions to be granted during a GitHub App's user-authorization web flow than was displayed to the user during approval. To exploit this vulnerability, an attacker would need to create a GitHub App on the instance and have a user authorize the application through the web authentication flow. All permissions being granted would properly be shown during the first authorization, but if the user later updated the set of repositories the app was installed on after the GitHub App had configured additional user-level permissions, those additional permissions would not be displayed, leading to more permissions being granted than the user potentially intended. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.3 and was fixed in versions 3.2.5, 3.1.13, 3.0.21. This vulnerability was reported via the GitHub Bug Bounty program.
Se ha identificado una vulnerabilidad de tergiversación de la interfaz de usuario en GitHub Enterprise Server que permitía conceder más permisos durante el flujo web de autorización de usuarios de una GitHub App de los que eran mostrados al usuario durante la aprobación. Para explotar esta vulnerabilidad, un atacante tendría que crear una GitHub App en la instancia y hacer que un usuario autorice la aplicación mediante el flujo de autenticación web. Todos los permisos concedidos serían mostrados correctamente durante la primera autorización, pero si el usuario actualizaba posteriormente el conjunto de repositorios en los que estaba instalada la aplicación después de que la aplicación de GitHub hubiera configurado permisos adicionales a nivel de usuario, esos permisos adicionales no serían mostrados, conllevando a una concesión de más permisos de los que el usuario podría haber previsto. Esta vulnerabilidad afectaba a todas las versiones de GitHub Enterprise Server anteriores a la 3.3 y fue corregido en las versiones 3.2.5, 3.1.13 y 3.0.21. Esta vulnerabilidad fue reportada por medio del programa GitHub Bug Bounty
