{"id":"CVE-2025-63680","details":"Nero BackItUp in the Nero Productline is vulnerable to a path parsing/UI rendering flaw (CWE-22) that, in combination with Windows ShellExecuteW fallback extension resolution, leads to arbitrary code execution when a user clicks a crafted entry. By creating a trailing-dot folder and placing a same-basename script, Nero BackItUp renders the file as a folder icon and then invokes ShellExecuteW, which executes the script via PATHEXT fallback (.COM/.EXE/.BAT/.CMD). The issue affects recent Nero BackItUp product lines (2019-2025 and earlier) and has been acknowledged by the vendor.","modified":"2026-03-13T03:40:53.026183Z","published":"2025-11-14T19:16:01.360Z","references":[{"type":"EVIDENCE","url":"https://github.com/PotatoHamm/Nero-Productline-Vulnerability"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-63680.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"2025"}]}]}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
