CVE-2021-22153

User-level command execution via CSV formula injection

Published May 13, 2021 · Updated Aug 3, 2024

CSV formula injection in BlackBerry UEM 12.13.1 QF2 and earlier and 12.12.1a QF6 and earlier allows local users to execute commands. The Management Console places attacker-controlled values into spreadsheet-exported data without neutralizing formula elements that the spreadsheet interprets as commands. A low-privileged user must supply crafted exportable data, and another user must export and open the resulting file in a spreadsheet application.
