CVE-2024-31212Public exploitNetwork attack vector

Administrative SQL injection via unsanitized period parameter

Published Apr 4, 2024 · Updated Aug 2, 2024

SQL injection in InstantCMS 2.16.2 allows remote authenticated users with administrative privileges to execute SQL via crafted period input. The index_chart_data action passes the unescaped period value to filterFunc, which embeds it directly in an SQL statement. An administrative session is required; successful exploitation permits database reads or writes allowed to the application's database account.
