Description
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.

Executive Summary

This vulnerability is an Arbitrary File Overwrite via Tar Extraction Path Traversal in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30 through 7000. The restore_mozzi_memories.sh script extracts user-controlled tar archives using the -C / flag, which causes the contents to be extracted to the filesystem root without validating the file paths. Attackers can exploit this by crafting malicious .tgz archives with path-traversed filenames (like etc/shadow or var/www/index.php) to overwrite critical system files, potentially leading to full system compromise.

Impact Analysis

This vulnerability can allow an attacker to overwrite critical system files on the affected device, leading to full system compromise. Because the attacker can control the contents of the tar archive and the extraction path, they can replace important files such as password files or web server files, potentially gaining unauthorized access, executing arbitrary code, or disrupting system operations.
