CVE-2023-45657Public exploitNetwork attack vector

Authenticated database disclosure via unescaped date parameters

Published Nov 6, 2023 · Updated Apr 28, 2026

SQL injection in POSIMYTH Innovations Nexter 2.0.3 and earlier allows remote authenticated users to read database data via crafted parameters. The request handler inserts user-controlled to and from values into an existing SQL query without sufficient escaping or prepared-statement binding. Subscriber-level access is required, and successful injection can append SQL clauses that disclose sensitive database content.
