CVE-2022-40472Public exploitNetwork attack vector

Code execution via exported CSV formula

Published Sep 29, 2022 · Updated May 20, 2025

CSV injection in ZKTeco ZKBio Time 8.0.7 and earlier allows remote authenticated users to execute code through exported reports. The Add New Message module stores the Content field without neutralizing spreadsheet formula prefixes and later emits the value into a CSV report. Exploitation requires login access and a report recipient to export the poisoned message, open the CSV in a spreadsheet, and approve its security warning.
