Summary
QNAP Download Station from 5.10.x before 5.10.1.312 and from 5.11.x before 5.11.2.321 is affected. An incorrect permission assignment (CWE-732) makes the script ds-move-files.sh writable, so a local attacker who already holds an administrator account can compromise the system. The CVSS 4.0 vector requires high privileges and no user interaction.
