Fortinet Issues Critical Patch for SQL Injection Vulnerability in FortiWeb (CVE-2025-25257)

July 11, 2025, United States

Fortinet has unveiled a patch addressing a severe security vulnerability in FortiWeb, which could allow unauthenticated attackers to execute arbitrary database commands on affected systems. Designated as CVE-2025-25257, this flaw has a CVSS score of 9.6 out of 10. According to Fortinet’s advisory, the vulnerability stems from “improper neutralization of special elements used in an SQL command (SQL Injection) [CWE-89],” enabling unauthorized SQL code execution through specially crafted HTTP or HTTPS requests.

The vulnerability affects the following FortiWeb versions:

  • FortiWeb 7.6.0 to 7.6.3 (Upgrade to 7.6.4 or higher)
  • FortiWeb 7.4.0 to 7.4.7 (Upgrade to 7.4.8 or higher)
  • FortiWeb 7.2.0 to 7.2.10 (Upgrade to 7.2.11 or higher)
  • FortiWeb 7.0.0 to 7.0.10 (Upgrade to 7.0.11 or higher)

Kentaro Kawane from GMO Cybersecurity is credited with reporting this significant vulnerability, as well as several critical issues in Cisco systems.

Fortinet Issues Critical Patch for SQL Injection Vulnerability in FortiWeb

On July 11, 2025, Fortinet announced the release of urgent patches for a significant security vulnerability in FortiWeb, a web application firewall. This flaw, designated CVE-2025-25257, poses a serious risk, allowing unauthorized attackers the potential to execute arbitrary SQL commands on affected systems. Scoring a critical 9.6 on the CVSS scale, this vulnerability could have widespread implications for businesses relying on FortiWeb for their web security.

The security advisory issued by Fortinet details that this security weakness arises from improper handling of special elements within SQL commands, a form of attack commonly referred to as SQL Injection (CWE-89). By exploiting crafted HTTP or HTTPS requests, an attacker could gain the ability to manipulate database interactions in a manner that bypasses authentication, effectively compromising the integrity of organizational data.

Impacted versions of FortiWeb include 7.6.0 to 7.6.3, requiring upgrades to 7.6.4 or later; versions 7.4.0 to 7.4.7 need to be updated to 7.4.8 or above; for those using 7.2.0 to 7.2.10, a transition to 7.2.11 or higher is necessary; and systems running versions 7.0.0 to 7.0.10 must upgrade to at least 7.0.11. Organizations still utilizing these vulnerable versions are strongly urged to implement the necessary updates to mitigate potential exploitation risks.

The primary targets of this vulnerability are likely organizations utilizing FortiWeb, which spans various sectors, including finance, healthcare, and e-commerce. Since Fortinet is based in the United States, the majority of the affected installations can be found domestically. However, due to the global reach of Fortinet’s user base, international entities could also be at risk if using outdated software.

From a cybersecurity perspective, this incident can be contextualized using the MITRE ATT&CK framework, notably within the tactics associated with initial access and exploitation of vulnerabilities. The ability of an attacker to execute unauthorized SQL commands suggests a clear pathway for initial access, leveraging SQL Injection techniques to manipulate databases without proper authentication. Furthermore, the potential for privilege escalation exists if attackers gain access to sensitive data or administrative functions during the exploitation.

The implications of this vulnerability extend beyond immediate data security concerns. Organizations must recognize the importance of timely patch management and the proactive measures necessary to safeguard their digital assets. As cyber threats continue to evolve, maintaining robust security practices and vigilant monitoring becomes increasingly critical for business continuity in a landscape rife with vulnerabilities.

As a response to this critical advisory, business owners are advised to take immediate action by reviewing their FortiWeb implementations and ensuring all updates are applied without delay. Cybersecurity is an ever-present challenge, and staying a step ahead is essential for protecting both organizational interests and customer trust.
