CVE-2019-25703Public exploitNetwork attack vector

Authenticated database disclosure via crafted bid parameter

Published Apr 12, 2026 · Updated Apr 12, 2026

Time-based blind SQL injection in ImpressCMS 1.3.11 allows remote authenticated users to read database data through a crafted bid value. The blocks-admin up operation at modules/system/admin.php treats the POST bid value as SQL syntax, as demonstrated by an injected SLEEP expression. A valid login and access to the blocks administration action are required; the timing oracle exposes database contents without returning query output directly.
