      "value": "ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the ZimaOS API endpoint `http://<Zima_Server_IP:PORT>/v3/file?token=<token>&files=<file_path>` is vulnerable to arbitrary file reading due to improper input validation. By manipulating the `files` parameter, authenticated users can read sensitive system files, including `/etc/shadow`, which contains password hashes for all users. This vulnerability exposes critical system data and poses a high risk for privilege escalation or system compromise. The vulnerability occurs because the API endpoint does not validate or restrict file paths provided via the `files` parameter. An attacker can exploit this by manipulating the file path to access sensitive files outside the intended directory. As of time of publication, no known patched versions are available."

      "value": "ZimaOS es una bifurcaci\u00f3n de CasaOS, un sistema operativo para dispositivos Zima y sistemas x86-64 con UEFI. En la versi\u00f3n 1.2.4 y todas las versiones anteriores, el endpoint de la API de ZimaOS `http:///v3/file?token=&amp;files=` es vulnerable a la lectura arbitraria de archivos debido a una validaci\u00f3n de entrada incorrecta. Al manipular el par\u00e1metro `files`, los usuarios autenticados pueden leer archivos confidenciales del sistema, incluido `/etc/shadow`, que contiene hashes de contrase\u00f1as para todos los usuarios. Esta vulnerabilidad expone datos cr\u00edticos del sistema y plantea un alto riesgo de escalada de privilegios o compromiso del sistema. La vulnerabilidad se produce porque el endpoint de la API no valida ni restringe las rutas de archivo proporcionadas a trav\u00e9s del par\u00e1metro `files`. Un atacante puede explotar esto manipulando la ruta del archivo para acceder a archivos confidenciales fuera del directorio previsto. Al momento de la publicaci\u00f3n, no hay versiones parcheadas conocidas disponibles."
