CVE-2021-41755Public exploitNetwork attack vector

Unauthenticated database query execution via kat1 injection

Published Jun 10, 2022 · Updated Aug 4, 2024

SQL injection in dynamicMarkt 3.10 and earlier allows remote attackers to execute database queries through the kat1 parameter in index.php. The signup path accepts kat1 in an index.php POST and evaluates a nested SQL sleep expression, showing that input reaches SQL execution without effective neutralization. No authentication is required; the published artifact demonstrates time-based query execution but does not establish direct data extraction or code execution.
