What is CVE-2025-25257?
CVE-2025-25257 represents a significant SQL Injection vulnerability found within the Fortinet FortiWeb product, specifically impacting versions 7.6.0 through 7.6.3, 7.4.0 through 7.4.7, 7.2.0 through 7.2.10, and any release below 7.0.10. FortiWeb is a web application firewall designed to protect applications from various security threats, ensuring the integrity and confidentiality of web-based services. The vulnerability arises from an inadequate handling of special characters within SQL commands, allowing unauthenticated attackers to execute malicious SQL code through specially crafted HTTP or HTTPS requests. This opens the door for unauthorized manipulation of database interactions, which can compromise data security and application functionality.
