CVE-2021-43735Public exploitNetwork attack vector

SQL injection via unsanitized behavior rules

Published Mar 23, 2022 · Updated Aug 4, 2024

SQL injection in CmsWing 1.3.7 allows remote authenticated users to execute database queries through a crafted behavior rule. The update_channel module stores an unvalidated SQL expression in the behavior rule's condition field, which a later navigation update evaluates. Administrative background access is required to plant the rule; the published proof of concept demonstrates a five-second time-based database version probe.
