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.\nThe `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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H/AU:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-22"],"references":["https://www.abdulmhsblog.com/posts/webfmvulns/"],"products":["dbbroadcast:mozart_dds_next_1000_firmware","dbbroadcast:mozart_dds_next_100_firmware","dbbroadcast:mozart_dds_next_2000_firmware","dbbroadcast:mozart_dds_next_3000_firmware","dbbroadcast:mozart_dds_next_300_firmware","dbbroadcast:mozart_dds_next_30_firmware","dbbroadcast:mozart_dds_next_3500_firmware","dbbroadcast:mozart_dds_next_500_firmware","dbbroadcast:mozart_dds_next_50_firmware","dbbroadcast:mozart_dds_next_6000_firmware","dbbroadcast:mozart_dds_next_7000_firmware","dbbroadcast:mozart_next_1000_firmware","dbbroadcast:mozart_next_100_firmware","dbbroadcast:mozart_next_2000_firmware","dbbroadcast:mozart_next_3000_firmware","dbbroadcast:mozart_next_300_firmware","dbbroadcast:mozart_next_30_firmware","dbbroadcast:mozart_next_3500_firmware","dbbroadcast:mozart_next_500_firmware","dbbroadcast:mozart_next_50_firmware","dbbroadcast:mozart_next_6000_firmware","dbbroadcast:mozart_next_7000_firmware"],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-66262","score":0.01424,"percentile":0.72717,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
