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."}], "lastModified": "2026-01-12T14:56:54.810", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nero:backitup:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C0417A0B-91DC-49AE-B1D5-0280F523AC70", "versionEndIncluding": "2025"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
