Descriptions

A remote code execution (RCE) vulnerability exists in the '/install_extension' endpoint of the parisneo/lollms-webui application, specifically within the `@router.post("/install_extension")` route handler. The vulnerability arises due to improper handling of the `name` parameter in the `ExtensionBuilder().build_extension()` method, which allows for local file inclusion (LFI) leading to arbitrary code execution. An attacker can exploit this vulnerability by crafting a malicious `name` parameter that causes the server to load and execute a `__init__.py` file from an arbitrary location, such as the upload directory for discussions. This vulnerability affects the latest version of parisneo/lollms-webui and can lead to remote code execution without requiring user interaction, especially when the application is exposed to an external endpoint or operated in headless mode.

Existe una vulnerabilidad de ejecución remota de código (RCE) en el endpoint '/install_extension' de la aplicación parisneo/lollms-webui, específicamente dentro del controlador de ruta `@router.post("/install_extension")`. La vulnerabilidad surge debido al manejo inadecuado del parámetro `name` en el método `ExtensionBuilder().build_extension()`, que permite la inclusión de archivos locales (LFI) que conducen a la ejecución de código arbitrario. Un atacante puede aprovechar esta vulnerabilidad creando un parámetro "nombre" malicioso que hace que el servidor cargue y ejecute un archivo "__init__.py" desde una ubicación arbitraria, como el directorio de carga para discusiones. Esta vulnerabilidad afecta a la última versión de parisneo/lollms-webui y puede provocar la ejecución remota de código sin requerir la interacción del usuario, especialmente cuando la aplicación está expuesta a un endpoint externo o se opera en modo sin cabeza.
