CVE-2025-25257 Scanner

Fortinet FortiWeb is a web application firewall utilized by businesses and organizations to protect their web applications from various cyber threats, including SQL injection, cross-site scripting, and other web-based exploits. It is designed to offer comprehensive web security management for applications and APIs, providing protective measures to ensure the integrity, availability, and confidentiality of data in transit and at rest. All business types and sectors recognize FortiWeb as a critical component in their network security architecture. FortiWeb's ability to inspect and filter HTTP/HTTPS traffic helps organizations thwart intrusions, ensuring that web applications are secure and compliant with security policies. It is constructed to meet the rigorous demands of any cloud-based or on-premises deployment, reinforcing security posture against diverse, continually evolving threats.

The SQL Injection vulnerability within FortiWeb arises from improper neutralization of special elements used in SQL commands. Attackers can exploit this vulnerability by sending crafted HTTP or HTTPS requests to execute unauthorized SQL commands. The vulnerability allows threat actors to alter database queries, potentially gaining unauthorized access to sensitive information or manipulating data within the database. If exploited successfully, this vulnerability can compromise system integrity and may lead to wider system exploitation activities. The vulnerability is particularly critical as it doesn't require user interaction or system privileges, increasing the ease with which it can be executed.

Technical details of this vulnerability reveal that attackers target endpoints using crafted requests that manipulate input data, which is improperly sanitized before being included in SQL queries. Vulnerabilities are often found in REST API endpoints, such as the `/api/fabric/device/status` endpoint within FortiWeb, where these endpoints accept unsanitized input. Because of the nature of SQL injection, this type of attack can easily evolve into more complex forms of exploitation, such as remote code execution if chained with other weaknesses. The vulnerability primarily relies on the misuse of SQL commands within these endpoints, causing execution of unintended database operations.

When exploited, this SQL Injection vulnerability can have serious repercussions for any organization using FortiWeb, including the unauthorized disclosure of sensitive data and systems compromise. An attacker could read, modify, or delete arbitrary data, facilitating further attacks against users connected to the vulnerable instance. Additionally, the compromise may open routes for attackers to implant malicious content or commands that change system behavior, establish persistent breaches, and exfiltrate confidential data. The credibility and operational continuity of businesses may be undermined if such vulnerabilities are leveraged successfully by cybercriminals.
