CVE-2025-66262

Arbitrary File Overwrite via Tar Extraction Path Traversal in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 allows an attacker to perform Tar extraction with -C / allow arbitrary file overwrite via crafted archive. The `restore_mozzi_memories.sh` script extracts user-controlled tar archives with `-C /` flag, depositing contents to the filesystem root without path validation. When combined with the unauthenticated file upload vulnerabilities (CVE-01, CVE-06, CVE-07), attackers can craft malicious .tgz archives containing path-traversed filenames (e.g., `etc/shadow`, `var/www/index.php`) to overwrite critical system files in writable directories, achieving full system compromise.

Summary
  • (es) Sobreescritura de archivo arbitrario mediante salto de ruta en extracción Tar en las versiones 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 del transmisor FM Mozart de DB Electronica Telecomunicazioni S.p.A. permite a un atacante realizar una extracción Tar con -C / y permitir la sobreescritura arbitraria de archivos mediante un archivo manipulado. El script 'restore_mozzi_memories.sh' extrae archivos tar controlados por el usuario con la bandera '-C /', depositando el contenido en la raíz del sistema de archivos sin validación de ruta. Cuando se combina con las vulnerabilidades de carga de archivos no autenticada (CVE-01, CVE-06, CVE-07), los atacantes pueden crear archivos .tgz maliciosos que contienen nombres de archivo con salto de ruta (por ejemplo, 'etc/shadow', 'var/www/index.php') para sobrescribir archivos críticos del sistema en directorios con permisos de escritura, logrando un compromiso total del sistema.
