CVE-2021-43851Network attack vector

Database disclosure and modification via unchecked POST parameters

Published Dec 21, 2021 · Updated Aug 4, 2024

SQL injection in Anuko Time Tracker 1.19.33.5606 and earlier allows remote authenticated users to read or modify database data. The groups.php handler passes an unchecked POST group value into a helper that interpolates it into an SQL query, while multiple status handlers accept unchecked status values. A valid account with subgroup or entity-management access is required, and exploitation can expose or alter application database records.
