Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-21107 is an Unquoted Search Path or Element vulnerability (CWE-428) affecting Dell NetWorker in versions prior to 19.11.0.3, including all versions of 19.10 and earlier. This flaw exists in the backup and recovery software, where the unquoted path in a search element allows unintended executable resolution during system operations.
A low-privileged attacker with local access can exploit this vulnerability with low complexity and no user interaction required, as indicated by its CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation enables arbitrary code execution with elevated privileges, potentially compromising the confidentiality, integrity, and availability of the affected system.
