CVE-2024-10082

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Authentication method confusion allows logging in as the built-in root user from an external service. The built-in root user up until 6.24.1 is generated in a weak manner, cannot be disabled, and has universal access.This vulnerability allows an attacker who can create an account on an enabled external authentication service, to log in as the root user, and access and control everything that can be controlled via the web interface. The attacker needs to acquire the username of the root user to be successful. This issue affects CodeChecker: through 6.24.1.

### Summary Authentication method confusion allows logging in as the built-in root user from an external service. The built-in root user is generated in a weak manner, cannot be disabled, and has universal access. ### Details Until CodeChecker version 6.24.1 there was an auto-generated super-user account that could not be disabled. The attacker needs to know only the username of the root user. This root user is unconditionally assigned superuser permissions. Which means that if any user via any service logs in with the root user's username, they will unconditionally have superuser permissions on the CodeChecker instance. The name of the user name can be found in `root.user` file in the CodeChecker configuration directory. You can check if you are impacted by checking the existence of this user in the external authentication services (e.g. LDAP, PAM etc.). ### Impact This vulnerability allows an attacker who can create an account on an enabled external authentication service, to log in as the root user, and access and control everything that can be controlled via the web interface. The attacker needs to acquire the username of the root user to be successful.

CodeChecker es una herramienta de análisis, una base de datos de defectos y una extensión de visualización para Clang Static Analyzer y Clang Tidy. La confusión del método de autenticación permite iniciar sesión como el usuario root integrado desde un servicio externo. El usuario root integrado hasta la versión 6.24.1 se genera de forma débil, no se puede deshabilitar y tiene acceso universal. Esta vulnerabilidad permite a un atacante que puede crear una cuenta en un servicio de autenticación externo habilitado iniciar sesión como el usuario root y acceder y controlar todo lo que se puede controlar a través de la interfaz web. El atacante necesita adquirir el nombre de usuario del usuario root para tener éxito. Este problema afecta a CodeChecker: hasta la versión 6.24.1.
